584c448b22 [chassisd]: Updated the API get_platform_info() to return running/detected ASIC's count (#16539)
previously, get_num_asics() returns the maximum number of asics. however, the asic_count 
should be actual number of asics populated which can be get from get_asic_presence_list().

edc1e48c17 sudo not required explicitly as /bin/ip netns identify is part of READ_ONLY_CMDS in sudoers file (#16115)
Why I did it
Few commands in multiasic platforms when run with the "sudo ip netns exec asic0 " option was taking like 15 mins to get the o/p. This behavior of sudo getting hung was seen by just doing this

jujoseph@svcstr-server-2:~ sudo ip netns exec asic0 bash
jujoseph@svcstr-server-2:~ sudo ls

deally sudo is not needed as we have /bin/ip netns identify present in /etc/sudoers file. Hence removing it

6876f27374 [Marvell] Fix get_system_mac for system without eeprom (#15376)
Why I did it
get_system_mac was returning 'None' mac for system without eeprom.
get_system_mac for marvell platform checks for mac in eeprom, profile.ini(hwsku file) and eth0. Check for valid mac returned by syseeprom was incorrect. Which was resulting in bypassing mac get from profile.ini and eth0.

How I did it
get_system_mac already has a logic to get first valid mac.
Removed null check for mac returned by eeprom.
Corrected the check for profile.ini file by checking if file exist.

How to verify it
Executed sonic-cfggen to check valid mac address is getting configured in config_db.json with/without profile.ini.

Add support data for fabric monitoring in CONFIG_DB. (#14170) (#16045)
Added support data for fabric monitoring in CONFIG_DB

The CONFIG_DB now has the FABRIC_MONITOR|FABRIC_MONITOR_DATA table for default value for fabric port monitoring. An example output of getting this table is:

sonic-db-cli CONFIG_DB hgetall "FABRIC_MONITOR|FABRIC_MONITOR_DATA"
{'monErrThreshCrcCells': '1', 'monErrThreshRxCells': '61035156', 'monPollThreshIsolation': '1', 'monPollThreshRecovery': '8'}

The CONFIG_DB now also has a table for each fabric port for its isolate status.
An example output of getting this table is:

sonic-db-cli CONFIG_DB hgetall "FABRIC_PORT|Fabric20"
{'alias': 'Fabric20', 'isolateStatus': 'False', 'lanes': '20'}

Finalize fast-reboot in warmboot finalizer (#14238)
- Why I did it
To solve an issue with upgrade with fast-reboot including FW upgrade which has been introduced since moving to fast-reboot over warm-reboot infrastructure.
As well, this introduces fast-reboot finalizing logic to determine fast-reboot is done.

- How I did it
Added logic to finalize-warmboot script to handle fast-reboot as well, this makes sense as using fast-reboot over warm-reboot this script will be invoked. The script will clear fast-reboot entry from state-db instead of previous implementation that relied on timer. The timer could expire in some scenarios between fast-reboot finished causing fallback to cold-reboot and possible crashes.

As well this PR updates all services/scripts reading fast-reboot state-db entry to look for the updated value representing fast-reboot is active.

- How to verify it
Run fast-reboot and check that fast-reboot entry exists in state-db right after startup and being cleared as warm-reboot is finalized and not due to a timer.

How I did it

And then, I would convert the mac from string to int and increase by 1, at last convert it to string with inserting ":".

Why I did it
VoQ chassis supervisor will have Fabric asics and the sub_role for fabric asics will be "Fabric".

container_checker on supervisor should check containers based on asic presence (#11442)
Why I did it
On a supervisor card in a chassis, syncd/teamd/swss/lldp etc dockers are created for each Switch Fabric card. However, not all chassis would have all the switch fabric cards present. In this case, only dockers for Switch Fabrics present would be created.

The monit 'container_checker' fails in this scenario as it is expecting dockers for all Switch Fabrics (based on NUM_ASIC defined in asic.conf file).

[multi-asic][cli][chassis-db] Avoid connecting to chassis db when cli commands are executed from linecards (#8065)
* [multi-asic][cli][chassis-db] Avoiding connecting to chassis db

Currently, for all the cli commands, we connect to all databases
mentioned in the database_config.json. The database_config.json also
includes the databases from chassis redis server from supervisor card.
It is unneccessary to connect to databases from chassis redis server
when cli commands are executed form linecard. But we need to allow
connection to chassis databases when the cli commands are executed from
supervisor card.

The changes in this PR fixes this problem. This PR requires that
asic.conf in supervisor card includes VOQ_SUPERVISOR with value 1 to
indentify the supervisor card. The connect_to_all_dbs_for_ns() is
changed to skip chassis databases form the list of collected databases
if the card is not supervisor card.

#### How I did it

Also remove unnecessary unittest-style setup and teardown functions from interface_test.py

[sonic-py-common.task_base] Provide ability to set stop timeouts (#6914)
#### Why I did it

Allowing an application to set a stop timeout for processes and threads provides the following benefits:

1. Prevents the application from hanging indefinitely in the case a process or thread does not exit
2. Allow ProcessTaskBase a chance to let the process exit gracefully before attempting to kill it

Default values are as follows:
- ProcessTaskBase: 1 second
- ThreadTaskBase: No timeout

#### How I did it

- Add optional `stop_timeout_secs` parameter to initializers of ProcessTaskBase and ThreadTaskBase
- Additionally:
    - Prefix private attributes with an underscore
    - Remove obsolete comments

[sonic-py-common] Add 'general' module with load_module_from_source() function (#7167)
#### Why I did it

To eliminate the need to write duplicate code in order to import a Python module from a source file.

#### How I did it

Add `general` module to sonic-py-common, which contains a `load_module_from_source()` function which supports both Python 2 and 3.

Call this new function in:
- sonic-ctrmgrd/tests/container_test.py
- sonic-ctrmgrd/tests/ctrmgr_tools_test.py
- sonic-host-services/tests/determine-reboot-cause_test.py
- sonic-host-services/tests/hostcfgd/hostcfgd_test.py
- sonic-host-services/tests/procdockerstatsd_test.py
- sonic-py-common/sonic_py_common/daemon_base.py

Fix Python 3 'importlib' bug; Add support for Python 2 back in sonic-py-common (#6933)
Fix a strange bug introduced by https://github.com/Azure/sonic-buildimage/pull/6832 which would only occur in environments with both Python 2 and Python 3 installed (e.g., the PMon container). Error messages such as the following would be seen:

```
ERR pmon#ledd[29]: Failed to load ledutil: module 'importlib' has no attribute 'machinery'
```

This is very odd, and it seems like the Python 2 version of importlib, which is basically just a stub, is taking precedence over the Python 3 version. I found that this occurs when calling `import importlib`. However, calling `import importlib.machinery` and `import importlib.util` causes the proper package to be referenced, and the `machinery` and `util` modules are loaded successfully. This is how it is specified in examples in the official documentation, however there is nothing mentioned regarding that it *should* be done this way or that `import importlib` is unreliable.

Also, since sonic-py-common is still used in environments with Python 2 installed we should maintain support for both Python 2 and 3 until we completely deprecate Python 2, so I have added this back in.
