Why I did it
To monitor the SSD health condition in DellEMC S6100 platform post upgrade.
A daemon is introduced to monitor the SSD every one hour.
To check for SSD status at boot time and at the time of cold-reboot.
All these changes are supported only for newer SSD firmware.
Added a platform_reboot_pre_check script to prevent cold-reboot based on SSD status.
Depends on Azure/sonic-utilities#1472

Closes issue #6982.
The issue was root caused as we were using the unix_socket for reading from DB as a default mechanism (#5250). The redis unix socket is created as follows.
admin@str--acs-1:~$ ls -lrt /var/run/redis/redis.sock
srwxrw---- 1 root redis 0 Mar 6 01:57 /var/run/redis/redis.sock
So it used to work fine for the user "root" or if user is part of redis group ( admin was made part of redis group by default )
Check if the user is with sudo permissions then use the redis unix socket, else fallback to tcp socket.
This PR is cherry-pick of master

Why I did it
Add support for BGP Monitors on multi asic SONiC platforms.
How I did it
On multi ASIC SONiC platforms, BGP monitor session will be established from Backend ASIC.
To achieve this following changes are done
Add BGP monitor configuration on the backend ASIC.
The BGP monitor configuration is present in the DPG of the device in minigraph.xml of multi-ASIC device, so this configuration will be added to the config_db of the host, when the minigraph is loaded.
To add configuration for this in the Backend ASIC, a new class MultiAsicBgpMonCfg is added to the hostcfgd service to update the config_db of the backend ASIC when the BGP_MONITOR table of the host config_db is updated.
This way incremental BGP_MONITOR configuration can also be handled.
Changes to establish BGP session with bgp monitor.
Add route in host main routing table to go to one of pre-define backend asic
Add IP table rule on front asic to mark the BGP packets with destination as IPv4 Loopback.
Add IP rule in front asic namespace to match mark BGP packet and lookup default table
Program the default route in FrontEnd asic name space docker default table as part of start.sh of the BGP container.
It need to be done as part of start.sh otherwise FRR default route will get over-written.

#### Why I did it
Change buffer config for new SKU Mellanox-SN2700-D40C8S8
#### How I did it
Reuse the buffer config of SKU Mellanox-SN2700-D48C8
#### How to verify it
Run sonic-mgmt qos test and all passed
This is to address the issue when "mmuconfig -p egress_lossy_profile" is executed which causes SYNCd failure with SAI_STATUS_INSUFFICIENT_RESOURCE for attr SAI_BUFFER_PROFILE_ATTR_RESERVED_BUFFER_SIZE.
This change also requires the change from (https://github.com/Azure/sonic-swss/pull/1649)
This SAI change was already tested as part of the (https://github.com/Azure/sonic-swss/pull/1649) PR.
1. Made the command next-hop-self force only applicable on back-end asic bgp. This is done so that BGPL iBGP session running on backend can send e-BGP learn nexthop. Back end asic FRR is able to recursively resolve the eBGP nexthop in its routing table since it knows about all the connected routes advertise from front end asic.
2. Made all front-end asic bgp use global loopback ip (Loopback0) as router id and back end asic bgp use Loopbacl4096 as ruter-id and originator id for Route-Reflector. This is done so that routes learnt by external peer do not see Loopback4096 as router id in show ip bgp <route-prerfix> output.
3. To handle above change need to pass Loopback4096 from BGP manager for jinja2 template generation. This was missing and this change/fix is needed for this also https://github.com/Azure/sonic-buildimage/blob/master/dockers/docker-fpm-frr/frr/bgpd/templates/dynamic/instance.conf.j2#L27
4. Enhancement to add mult_asic specific bgpd template generation unit test cases.

Fix Issue #6537
- Why I did it
Current mutli-asic vs hwsku consists of 6 asics with each asic having 32 interfaces. When bringing this up, below issue was seen:
When all 32 interfaces(sonic interfaces and linux interface) are set to 9100 mtu, DMA error is seen "DMA: Out of SW-IOMMU space for 4096 bytes at device 0000:06:03.0" which can be fixed by updating swiotlb=65536 in /host/grub/grub.cfg .In order to keep multi-asic VS lighter and easier to bring up and test, new hwsku 'msft_four_asic_vs' is added to represent 4-asic hwsku with 2 frontend asics and 2 backend asics and each asic having 8 interfaces interconnected by port-channels.
- How I did it
Add msft_four_asic_hwsku directory to have the right number of directories (4) and update port_config.ini and lanemap.ini files to include 8 ports information.
Add topology.sh script to create the internal asic-asic connectivity.
- How to verify it
Update asic.conf with the 4 asic information as below and build sonic-vs.img:
NUM_ASIC=4
DEV_ID_ASIC_0=0
DEV_ID_ASIC_1=1
DEV_ID_ASIC_2=2
DEV_ID_ASIC_3=3
Modify sonic_multiasic.xml to have 8 front panel interfaces.
create virtual switch using "sudo virsh sonic_mutliasic.xml" command.
Start topology service and Load config_db files for switch and each asic.
Ensure that that all internal interfaces and port_channels are coming up.
multi-asic vs testbed:
Bring up mutli-asic VS testbed with a multi-asic image(asic.conf updated to 4 asics) and using t1-lag topology.
./testbed-cli.sh -t vtestbed.csv -m veos_vtb -k ceos add-topo vms-kvm-four-asic-t1-lag password.txt
Load minigraph/config_dbs.
Ensure all internal and external interfaces come up.
No change on single asic vs.

Update topology script to retrieve hwsku from minigraph
if hwsku information is not available in config_db.
Fix clean up of interfaces in msft_multi_asic_vs hwsku
topology script.
- Why I did it
When bringing up multi-asic VS switch, topology service is started during boot up.
Topology service starts a shell script which runs the topology script present in /usr/share/sonic/device// directory. To invoke hwsku specific script, the topology script tries to retrieve hwsku information from config_db.
During initial boot up config_db might not be populated. In order to start topology service before config_db is updated,
update topology script to get hwsku information from minigraph.xml if it is available.
This will be helpful to bring up multi-asic VS testbed by loading minigraph and starting topology service.
- How I did it
Update topology.sh script to retrieve hwsku information from minigraph.xml.
Fix clean up function on msft_multi_asic_vs toplogy script.
- How to verify it
single-asic VS - no change; topology service is only enabled for multi-asic VS.
multi-asic VS - Bring up multi-asic VS image, copy minigraph to vs image, start topology service. Topology service should be successful.
to test clean up function fix, start topology service - make sure interfaces are created and moved to the right namespaces.
stop topology service - make sure namespace do not have any interface and all front end interfaces are present in default namespace.
What I did:-
For multi-asic platforms added iptable v4 rule to communicate on docker bridge ip
For multi-asic platforms extend iptable v4 rule for iptable v6 also
For multi-asic program made all internal rules applicable for all protocols (not filter based on tcp/udp). This is done to be consistent same as local host rule
For multi-asic platforms made nat rule (to forward traffic from namespace to host) generic for all protocols and also use Source IP if present for matching

[multi_asic][vs]: Add dependency in teamd service to start after topology service.
- Why I did it
In multi-asic VS, topology service is run after database service to set up the internal asic topology.
swss and syncd have a dependency to start after topology service is run so that the interfaces are moved to right namespace and created in the right namespace. In case of multi-asic vs, during the initial boot up, when there is no configuration added, teamd service starts and swss/syncd do not start as topology service does not start. Upon loading configuration using config_db or minigraph, swss and sycnd start up , but teamd is not restarted as swss is not stopped and started. This causes teamd to be in a bad state and requires a reload of config.
- How I did it
Add dependency in teamd service to start after topology service is completed.
- How to verify it
No change in single asic vs or platform.
No change in multi-asic regular image.
Change only in multi-asic VS. Bring up a multi-asic VS image without any configration, teamd service will fail to start due to dependency failure. Load minigraph, start topology service, load configuration, ensure all services come up.
