[build arm] fix sonic-slave-buster build break (#6469)
When building the sonic-slave-buster docker container, the node.js package is
installed to meet the requirements of the Azure DevOPs pipleline
build. Recently this install of node.js has been failing.

This commit fixes that build break by upgrading the
sonic-slave-buster build to install version 14.x of node.js which is the
current LTS version for buster.

[Mellanox] Make determine-reboot-cause service start after hw-management service (#6465)
**- Why I did it**

On the Mellanox platform, reboot cause is fetched from some certain sysfs which is created by the hw-management service. So determine-reboot-cause service shall start after hw-management, otherwise it could fail due to the related sysfs is not available yet.

**- How I did it**

Add a patch to the hw-management service to make sure determine-reboot-cause service should start after it.

Export libyang API "lyd_check_mandatory_tree" for Management framework (CVL) (#5714)
- Why I did it
Management framework (CVL) needs to call lyd_check_mandatory_tree() for validation and hence exported lyd_check_mandatory_tree() as an API.

- How I did it
Added "API" keyword before lyd_check_mandatory_tree() definition.

- How to verify it
There is no functionality code change here and no specific steps to verify it. Management framework (CVL) should be able to call this function and no patching and compilation error should be seen.

- Description for the changelog
Added "API" keyword before export lyd_check_mandatory_tree() function definition.

[docker-frr]: Use egrep with regexp to match correct TSA rules (#6403)
**- Why I did it**
Earlier today we found a bug in the SONiC TSA implementation.
TSC shows incorrect output (see below) in case we have a route-map which contains TSA route-map as a prefix.
```
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Not consistent
```
The reason is that TSC implementation has too loose regexps in TSA utilities, which match wrong route-map entries:
For example, current TSC matches following
```
route-map TO_BGP_PEER_V4 permit 200
route-map TO_BGP_PEER_V6 permit 200
```
But it should match only
```
route-map TO_BGP_PEER_V4 permit 20
route-map TO_BGP_PEER_V4 deny 30
route-map TO_BGP_PEER_V6 permit 20
route-map TO_BGP_PEER_V6 deny 30
```

**- How I did it**
I fixed it by using egrep with `^` and `$` regexp markers which match begin and end of the line.

**- How to verify it**
1. Add follwing entry to FRR config:
```
str-s6100-acs-1# 
str-s6100-acs-1# conf t
str-s6100-acs-1(config)# route-map TO_BGP_PEER_V4 permit 200 
str-s6100-acs-1(config-route-map)# end
```
2. Use the TSC command and check output. It should show normal.
```
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Normal```

Remove things needed for building Python 3 from source (#6441)
**- Why I did it**

Prior to SONiC using Debian Buster, we needed to build Python 3.5 or newer from source for installation in the SNMP container, becuase it wasn't available from the Debian repository for Jessie or Stretch. Now that all containers are based on Buster, we simply install Python 3.7 from the Debian repository in the host as well as all containers. We are no longer building Python 3 from source, so the Makefile is unused and we no longer need to install build dependencies in the slave containers.

**- How I did it**

- Remove Python 3 makefile
- No longer install Python 3 build dependencies in the slave containers.

[swss] Depend on Python 3 version of swsscommon rather than Python 2 (#6432)
The only Python code in the SwSS package, restore_neighbors.py, was recently converted to Python 3 and most dependencies were updated as part of #6207. However, the SwSS makefile still listed the Python 2 version of the swsscommon package as a dependency. This caused Python 2-related packages to be installed in containers unnecessarily.

[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.

[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.
