interfaces-config service configures lo address. If bgp service
starts before lo address is configured, then following config

The adds a few seconds delay in bgp service start
We noticed in tests/production that there is a low probability failure
where /etc/hosts could have some garbage characters before the entry for
local host name. The consequence is that all sudo command would be very
slow. In extreme cases it would prevent some services from starting
properly.
I suspect that the /etc/hosts file might be opened by some process causing
the issue. Editing contents with new file level and replace the whole file
should be safer.

- What I did
This fix removes the possibility of 'localhost' entry getting removed from /etc/hosts file by hostname-config service.
Without this change, whenever we change the hostname from 'localhost' to any other name on the config_db.json and reload the config, /etc/hosts file will only have the new hostname on it. But there are multiple sonic utilities (eg: swssconfig) which relies on the hard coded 'localhost' name and they tend to stop working.
- How I did it
Added a new check on hostname-config.sh script to avid blindly deleting the line containing the old hostname from /etc/hosts file. Now it will delete the old hostname only if its not localhost or when the hostname is not changing.
- How to verify it
Bring up SONiC on a device with hostname as localhost
Edit /etc/sonic/config_db.json to update the 'hostname' filed under DEVICE_METADATA from "hostname" : "localhost" --> "hostname" : "sonic"
run config reload -y to reflect the hostname change done on config_db.json file.
cat /etc/hosts and check whether both 127.0.0.1 localhost and 127.0.0.1 sonic entry are present on the file.
ping localhost should work fine.
- Description for the changelog
Make hostname-config service more robust in handling SONiC hostname change from localhost to anything else.
- after reloading minigraph, write latest version string in the DB.
- if old config_db.json file exists, use it and migrate to latest version.
- only reload minigraph when config_db.json doesn't exist and minigraph
exists.

* Add debug docker for SNMP.
* Removed a redundant install of debug packages.
Propagate the debug flag to template file to mount /dbg & /src to debug containers.

- monit config broke by one monit upgrade
- abandon sed approach since it is suspestible to monit config changes
- use unixsocket instead of httpd due to a bug in 5.20.0
[build_debian] Generate checksum of ASIC config files

radv should be left alone during warm restart of swss. Otherwise it will
announce departure and cause hosts to lose default gateway.

Present: Servers are listed in the same order as in redis-db
Fix: Save the sort o/p, hence use sorted list to write into pam.d's conf.
As well convert priority to integer for use by sort.
* [service dependent] describe non-warm-reboot dependency outside systemctl
When dependency was described with systemctl, it will kick in all the time,
including under warm reboot/restart scenarios. This is not what we always
want. For components that are capable of warm reboot/start, they need to
describe dependency in service files.

* [service] teamd service should not require swss service
Adding require swss will cause teamd to be killed by systemctl when swss

* [warm reboot] save configuration after warm reboot
After warm reboot, save a copy of in memory database to config_db.json,
upgrade procedure might have removed config_db.json to force new image
to reload minigraph. However, reload minigraph is skipped during warm
reboot. Missing config_db.json would cause device to fault in next
non-upgrading cold/fast reboot.

* Update finalize-warmboot.sh
* backport new platform api to 201811, reboot cause part
* install new platform api on host
* 1. remove chassis's dependency on sonic_platform_daemon.
2. add some mellanox-specific hardware reboot causes.
3. fix typo in files/image_config/process-reboot-cause/process-reboot-cause.
* 1. add dependency of sonic_platform for base image
2. handle the case of reboot cause file not found
* adjust log message.
In case of going from previous iteration of SONiC, and the last reboot
was hardware, REBOOT_CAUSE_FILE may not be present and the service may
throw an error.
- Make sure that migrated DB contents persisted for next boot
- Make sure that db saved after warm reboot.

* fix fast reboot compatibility
We should handle both cases for backward-compatible with 201803:
- fast-reboot
- SONIC_BOOT_TYPE=fast-reboot
* handle review comments
* add a comment that getBootType code snippet is shared between two files
* [submodule] update sonic-linux-kernel (#2985)
* Fix many version strings
* Update minor version
* Update arista-drivers submodule (#9)
* Rebuild SDK on new kernel (#10)
* [logrotate] Decrease frequency to every 10 minutes; kill any lingering logrotate processes
* [logrotate] Delete all *.1.gz files as firstaction; Remove note about init-system-helpers < 1.47 workaround
However, continue to send SIGHUP directly to rsyslogd process
because 'service rsyslog rotate' still doesn't work properly with
init-system-helpers version 1.48
* Switch the nss look up order as "compat" followed by "tacplus".
This helps use the legacy passwd file for user info and go to tacacs only if not found.
This means, we never contact tacacs for local users like "admin".
This isolates local users from any issues with tacacs servers.
W/o this fix, the sudo commands by local users could take <count of servers> * <tacacs timeout> seconds, if the tacacs servers are unreachable.
* Skip tacacs server access for local non-tacacs users.
Revert the order of 'compat tacplus' to original 'tacplus compat' as tacplus
access is required for all tacacs users, who also get created locally.
- Add ebtables package, and install some filter rules:
1. ebtables -A FORWARD -d BGA -j DROP
2. ebtables -A FORWARD -p ARP -j DROP
Basically, we let the ARP packets in the VLAN being forwarded by the ASIC,
kernel gets a copy of these ARP packets and the forwarding from Kenerl gets
dropped. So there is always only one copy of ARP/response in the VLAN.
