Added support for Mellanox-SN2700 based SKU for docker-sonic-vs and to differentiate platform based on hw-sku rather than on fake_platform in VS.
Currently SAI VS library uses hwsku based SAI profile to differentiate and mock different platform implementations. The same functionality in swss is achieved using a fake_platform env variable.
Using a fake_platform has some drawbacks that the vs container appears to still use a different vendor hw-sku

In order to unify the approach at both swss and vs SAI and to be uniform throughout this PR introduces the approach of using hw-sku to differentiate different platforms. This requires support for Mellanox-SN2700 HWSKU for Mellanox platform which is also addressed by this PR.

- Why I did it
In case an app.ext requires a dependency syncd^1.0.0, the RPC version of syncd will not satisfy this constraint, since 1.0.0-rpc < 1.0.0. This is not correct to put 'rpc' as a prerelease identifier. Instead put 'rpc' as build metadata in the version: 1.0.0+rpc which satisfies the constraint ^1.0.0.
- How I did it
Changed the way how to version in RPC and DBG images are constructed.
- How to verify it
Install app.ext with syncd^1.0.0 dependency on a switch with RPC syncd docker.

- Why I did it
docker-orchagent was missing libsairedis version label.
E.g. Currently only swsscommon is recorded in the labels:
admin@arc-switch1038:~$ docker inspect docker-orchagent | grep versions
"com.azure.sonic.versions.libswsscommon": "1.0.0"
With this change libsairedis is also recorded:
admin@arc-switch1038:~$ docker inspect docker-orchagent | grep versions
"com.azure.sonic.versions.libswsscommon": "1.0.0"
"com.azure.sonic.versions.libsairedis": "1.0.0"
- How I did it
By expanding the list of dependencies.
- How to verify it
Build and verify the label for libsairedis exists in docker-orchagent.

- Why I did it
Wrong SKU configuration will lead to longer init flow.
This will affect fast-reboot feature by increasing the traffic downtime.
Since MLNX met the required downtime period with this SKU this bug found with a delay.
- How I did it
Add the required split labels for ports.
- How to verify it
Run fast-reboot with this platform using SN3800-D112C8 SKU.

```
#### Why I did it
Fixes https://github.com/Azure/sonic-buildimage/issues/8619
#### How I did it
1) Listening to CFG_DB notifications was migrated from ConfigDBConnector to SubscriberStateTable & Select
2) This change in design helped me to remove `update_all_features_config` which was roughly taking a 5-10 sec time to execute and thus the reason for blackout
3) Edited FeatureHandler, Feature & NtpCfgd classes to suit this design
4) Added corresponding mocks and UT's
**Changes made to classes other than HostConfigDaemon:**
With the previous design, the initially read data from the config db was applied by using hardcoded methods even before the config_db.listen() was called. For Eg: `update_all_features_config` for FeatureHandler and load() named methods for NtpCfgd etc
But with this design, since the existing data is read and given out as a notification by SubscriberStateTable, i've pretty much removed these hardcoded methods. Thus changes made to these class will be around adapting them to the new design and no change in the actual functionality .
#### How to verify it
UT's:
```

tests/procdockerstatsd_test.py . [ 32%]

Why I did it
Storage T0's have all vlan members as tagged
How I did it
Since currently minigraph does not have a unique way to identify if a vlan member is tagged/untagged and to ensure other scenarios are not broken, the logic used is to just update the vlan member type as 'tagged' when we determine that it is a storage backend device. This change will apply only to storage backend T0's since storage backend T1's will not have vlan member information
How to verify it
Updated the storage backend T0 testcases to check for tagged vlan members
Added testcase to check if a T1 and backend T1 device generates an empty vlan member table
Existing vlan member testcases are good enough for checking if any regression has been caused for regular T0's
Build sonic_config_engine-1.0-py3-none-any.whl successfully
#### Why I did it
Fixed an issue that changing SDK version leads to cache framework taking cached syncd RPC image rather then rebuilding syncd RPC based on new syncd with new SDK.
Investigation showed that cache framework calculates a component hash based on direct dependencies. Syncd RPC image hash consists of two parts: one is the flags of syncd RPC (platform, ENABLE_SYNCD_RPC) and syncd RPC direct dependencies makefiles. None of the syncd RPC direct dependencies are modified when SDK version changes, so hash is unchanged.
#### How I did it
To fix this issue, include the hash of dependencies into current component hash calculation, e.g.:
In calcultation of the hash ```docker-syncd-mlnx-rpc.gz-274dfed3f52f2effa9989fc-39344350436f9b06d28b470.tgz```, the hash of syncd is included: ```docker-syncd-mlnx.gz-48ee88ac54b201e0e107b15-7bbea320025177a2121e440.tgz``` in which the hash of SDK is included.
#### How to verify it
Build with cache enabled and check that changing SDK version leads to a different hash of syncd rpc image:
SDK version 4.5.1002:
```
docker-syncd-mlnx.gz-48ee88ac54b201e0e107b15-7bbea320025177a2121e440.tgz
docker-syncd-mlnx-rpc.gz-274dfed3f52f2effa9989fc-39344350436f9b06d28b470.tgz
```
SDK version 4.5.1002-005:
```
docker-syncd-mlnx.gz-18baf952e3e0eda7cda7c3c-e5668f4784390d5dffd55af.tgz
docker-syncd-mlnx-rpc.gz-4a6e59580eda110b5709449-552f76be135deaf750aeab2.tgz

* [Nokia ixs7215] Platform API fixes
This commit delivers the following fixes
- Fix bug preventing access to second PSU eeprom
- Fix bug preventing updates to front panel PSU status led
- Fix SFP reset test case failure
* Fix LGTM alert
This commit more fully declares the HW capabilities of the Nokia-7215
platform. For example, support for the threshold values associated with each
thermal sensor is described. The intent here is to inform the sonic-mgmt
platform test cases of which HW features are supported.
This commit must align with PR# 4521 within the sonic-mgmt git repo which is
currently under review. Any changes to that PR will need to be reflected in
this commit.
Add code to interfaces-config.sh to configure eth1 in multi-asic
containers so that they can access midplane subnet.

Fixed issue introduced by PR#7857. The problem was that introduction of

init_config.json and virtual chassis default_config.json

Also, in the wait script, wait 10 additional seconds after the vlans,
port channels, and any interfaces are up. This is because dhcrelay
listens on all interfaces (in addition to port channels and vlans), and
to ensure that it stays in a clean state during runtime, wait some extra
time to make sure that those interfaces are created as well.
