- 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.

The start template script that this value is used in will determine what

With Docker 20.10, if --net=host is specified twice in docker run, then
it errors out. Therefore, remove the explicit --net=host in the run

How I did it
Added the configuration, API changes to support system health
How to verify it

Why I did it

How to verify it
Run platform test suite after making the changes.
This change is to add a gbsyncd container to accommodate the syncd process and the SAI libraries for the Credo gearbox chips.
How I did it
This container works similar to the existing Broadcom syncd container. Its main difference is that the SAI-related dynamic libraries are replaced by the ones for Credo gearbox chips, and the container only reacts to SAI events for the gearbox chips. The SAI libraries will be provided by the package libsai-credo_1.0_amd64.deb.
For the image build, the added container will be built and included in the Broadcom platform image, after $(LIBSAI_CREDO)_URL = is replaced to the correct value. For now, as $(LIBSAI_CREDO)_URL is empty, the container build is skipped in the image build.
After the container is included in the image, in the runtime, the container will begin with checking the existence of /usr/share/sonic/hwsku/gearbox_config.json; if that file is not provided, the container will exit by itself. Therefore, for platforms unrelated to the Credo chips, as long as they are not providing the file, they will not be affected by this change.
Why I did it
Added a check in determining CPU reset in fast-/warm-reboot in their respective platform plugin.
Introducing reboot plugin for "reboot" command to handle its own platform plugin.

CS00012019578 Pre FEC bit-error rate (BER) - DNX and XGS (TD and TH 50/100G)
#### Why I did it
- After [sonic-linux-kernel#177](https://github.com/Azure/sonic-linux-kernel/pull/177) changes, the I2C mux channels of Baseboard and Switchboard CPLDs are moved from i2c-4 and i2c-5 to i2c-36 and i2c-37 respectively.
- This caused QSFP driver initialization of i2c-36 to i2c-41 to fail causing the ports from Ethernet208 to Ethernet248 fail.
#### How I did it
- The fix to this problem is to change the order of QSFP driver initialization to I2C mux channels.
- Instead of the order i2c-10 to i2c-41, the order i2c-4 to i2c-35 is being utilized.
- Also, need to change the i2c-mux-channel number for Baseboard CPLD and switchboard CPLD in scripts to access them.

LED_PROC_INIT_SOC variable was incorrectly referenced as LED_SOC_INIT_SOC. Introduced in #5483

* 7260cx3 DualToR config.bcm support based on DualToR setting in device metadata at boot time.
For HWSKU Arista-7260CX3-C64 the MMU setting SOC for T0/T1 is also combined into the config.bcm.j2 logic so use just one config file and adding delta based on Switch Roles.
