[Nokia ixs7215] Add SW assist for platform entropy & fix inband mgmt support (#6417)
- Improve random number generation during early Sonic initialization by providing SW updates to Linux entropy value.
- Improve handling of platform In-Band management port

This commit provides the following updates to the Nokia ixs7215 platform

1. The Marvell Armada-38x SOC requires SW assistance to improve the system
   entropy value available early on in the Sonic boot sequence.
2. The Nokia ixs7215 platform does not have a dedicated Out-Of-Band (OOB) mgmt
   port and thus requires additional logic to optionally support configuring
   front panel port 48 as an In-Band mgmt port. This commit provides additional
   logic to manage and maintain the operation of this In-Band mgmt port.

[Platform][nokia]: python3-smbus package add with python3 and jinja fixes (#6416)
fix platform driver breakage due to python3 upgrade and fix load minigraph errors with config load_minigraph -y

**- How I did it**
added python3-smbus to the pmon docker template since the previous was python2 specific 
fixed additional "ord" python2 specific code 
fixed the jinja templates used by qos reload - the template logic required data to be parsed 

**- How to verify it**
run "show platform XXX" commands and verify output
run "sudo config load_minigraph -y" and verify configuration 
run "show interfaces XXX" and verify output

[build]: fix dpkg admindir corruption issue in parallel build (#6408)
Fix #119

when parallel build is enable, multiple dpkg-buildpackage
instances are running at the same time. /var/lib/dpkg is shared
by all instances and the /var/lib/dpkg/updates could be corrupted
and cause the build failure.

the fix is to use overlay fs to mount separate /var/lib/dpkg
for each dpkg-buildpackage instance so that they are not affecting
each other.

[Monit] Monitoring the running status of containers. (#6251)
**- Why I did it**
This PR aims to monitor the running status of each container. Currently the auto-restart feature was enabled. If a critical process exited unexpected, the container will be restarted. If the container was restarted 3 times during 20 minutes, then it will not run anymore unless we cleared the flag using the command `sudo systemctl reset-failed <container_name>` manually. 

**- How I did it**
We will employ Monit to monitor a script. This script will generate the expected running container list and compare it with the current running containers. If there are containers which were expected to run but were not running, then an alerting message will be written into syslog.

**- How to verify it**
I tested this feature on a lab device `str-a7050-acs-3` which has single ASIC and `str2-n3164-acs-3` which has a Multi-ASIC. First I manually stopped a container by running the command `sudo systemctl stop <container_name>`, then I checked whether there was an alerting message in the syslog.

Take a copy of existing TACACS credentials and restore it during upgrade (#6285)
In scenario where upgrade gets config from minigraph, it could miss tacacs credentials as they are not in minigraph. Hence restore explicitly upon load-minigraph, if present.

- Why I did it
Upon boot, when config migration is required, the switch could load config from minigraph. The config-load from minigraph would wipe off TACACS key and disable login via TACACS, which would disable all remote user access. This change, would re-configure the TACACS if there is a saved copy available.

- How I did it
When config is loaded from minigraph, look for a TACACS credentials back up (tacacs.json) under /etc/sonic/old_config. If present, load the credentials into running config, before config-save is called.

- How to verify it
Remove /etc/sonic/config_db.json and do an image update. Upon reboot, w/o this change, you would not be able ssh in as remote user. You may login as admin and check out, "show tacacs" & "show aaa" to verify that tacacs-key is missing and login is not enabled for tacacs.
With this change applied, remove /etc/sonic/config_db.json, but save tacacs & aaa credentials as tacacs.json in /etc/sonic/. Upon reboot, you should see remote user access possible.

[system-health] Make run_command() Python 3-compliant (#6371)
Pass universal_newlines=True parameter to subprocess.Popen(); no longer use .encode('utf-8') on resulting stdout.
This was missed in #5886

Note: I would prefer to use text=True instead of universal_newlines=True, as the former is an alias only available in Python 3 and is more understandable than the latter. However, Even though the setup.py file for this package only specifies Python 3, the LGTM tool finds other Python 2 code in the repo and validates the code as Python 2 code and alerts that text=True is an invalid parameter. Will stick with universal_newlines=True for now. Once all Python code in the repo has been converted to Python 3, I will change all universal_newlines=True to text=True.

[brcm]: BRCM SAI 4.2.1.5-9 Fix _brcm_sai_indexed_data_get () with unexpected queue causing _brcm_sai_switch_assert () after warm reboot (#6374)
Starting from build (master) 176 the warm reboot on BRCM Platform started to experience syncd crash. Upon further debug by Ying it was determined that the crash was related to the following new change:
[Dynamic buffer calc] Support dynamic buffer calculation (#1338)

Ying also debugged further and found The crash was caused by buffer pool profile setting operation SAI_BUFFER_PROFILE_ATTR_SHARED_DYNAMIC_TH

A case has filed with BRCM while a potential fix was tried by Ying that seems to have addressed this issue and we are making this change available in master branch so that it will allow further feature validation/testing especially in the warm reboot area.
Once an official fix is provided by BRCM, we will then remove this in house fix and apply the official fix.

- How to verify it
Just perform warm reboot with any master code 175 or above you should see this issue or issue the following cmd will also cause the crash: "mmuconfig -p egress_lossy_profile -a 0"

[snmp]: updated to support snmp config from redis configdb (#6134)
**- Why I did it**
I'm updating the jinja2 template to support getting SNMP information from the redis configdb. 
I'm using the format approved here: 
https://github.com/Azure/SONiC/pull/718

This will pave the way for us to decrement using the snmp.yml in the future.  
Right now we will still be using both the snmp.yml and configdb to get variable information in order to create the snmpd.conf via the sonic-cfggen tool. 

**- How I did it**
I first updated the SNMP Schema in PR #718 to get that approved as a standardized format. 
Then I verified I could add snmp configs to the configdb using this standard schema.  Once the configs were added to the configdb then I updated the snmpd.conf.j2 file to support the updates via the configdb while still using the variables in the snmp.yml file in parallel.  This way we will have backward compatibility until we can fully migrate to the configdb only. 

By updating the snmpd.conf.j2 template and running the sonic-cfggen tool the snmpd.conf gets generated with using the values in both the configdb and snmp.yml file.

[libyang1] Adding LFS support for arm32 (#6346)
In the emulated armhf environment, the function readdir()returns NULL on a ext4 file system directory. When running the libyang1 test cases, it will require to load the plugins from the files (such as metadata.so), because the readdir() is failing, the plugins can’t be loaded in the emulated armhf environment, so it causes libyang1 test error. This error is a combination of the following reasons.
• Emulation of a 32-bit target from a 64-bit host –> qemu from x86_64 to armhf
• Glibc version > 2.27 – Debian buster is using glibc 2.28

- How I did it
Enabled large file support by setting _FILE_OFFSET_BITS=64 for libyang1.

ae2cb47091 [build]: add artifical dependency between libyang and frr
frr build requires libyang 1.0.184 which conflicts with
libyang 1.0.73. Solution here is to compile frr and libyang 1.0.184
first, and then uninstall libyang 1.0.184 after frr build.
Then, compile libyang 1.0.73 and all packages depend on it later.
