Pass additional parameter "%P" - pid of the process in the initial namespace, which is host. (#5301)
This would enable the coredump_compress script to retrieve additional info regarding the crashing process.

[redis] Add redis Group And Grant Read/Write Access to Members (#5289)
sonic-cfggen is now using Unix Domain Socket for Redis DB. The socket
is created using root account. Subsequently, services that are started
as admin fails to start. This PR creates redis group and add admin
user to redis group. It also grants read/write access on redis.sock
for redis group members.

[radvd] No longer build from source; Install vanilla Debian package once again (#5242)
Remove radvd Makefile and patch, change docker-router-advertiser Dockerfile template to simply install the vanilla radvd package using apt-get.

- In PR https://github.com/Azure/sonic-buildimage/pull/2795, we started building radvd from source and patching it to prevent it from erroring out when advertising an MTU of 9100 which was greater than the MTU size configured on the bridge interface (1500), which was due to a limitation in the 4.9 Linux kernel.
- Master branch is now using Linux kernel 4.19. As of 4.18, the kernel supports setting a bridge MTU to a value > 1500.
- PR https://github.com/Azure/sonic-swss/pull/1393 modified vlanmgrd to take advantage of this and now configures the MTU of bridge interfaces in SONiC to the proper size of 9100. Therefore, we no longer need to patch radvd. Since we no longer need to patch radvd, we no longer need to build it from source, so we can save build time by going back to simply installing the vanilla radvd Debian package in the router-advertiser container.

[docker-sonic-vs] Create /usr/share/sonic/platform symlink (#5268)
Copying platform.json file into an empty /usr/share/sonic/platform directory does not mimic an actual device. A more correct approach is to create a /usr/share/sonic/platform symlink which links to the actual platform directory; this is more like what is done inside SONiC containers. Then, we only need to copy the platform.json file into the actual platform directory; the symlink takes care of the alternative path, and also exposes all the other files in the platform directory.

[docker-sonic-vs] Set PLATFORM and HWSKU env vars in Dockerfile (#5266)
sonic-py-common package relies on the `PLATFORM` environment variable to be set at runtime in the SONiC VS container. Exporting the variables in the start.sh script causes the variables to only be available to the shell running start.sh and any subshells it spawns. However, once the script exits, the variable is lost. This is resulting in the failure of tests which are run in the VS container, as they call applications which in turn call sonic-py-common functions which rely on PLATFORM to be set.

Setting the environment variables in the Dockerfile allows them to persist through the entire runtime of the container.

[sonic-py-common] Add unit test framework (#5238)
**- Why I did it**

To install the framework for adding unit tests to the sonic-py-common package and report coverage.

** How I did it **

- Incorporate pytest and pytest-cov into sonic-py-common package build
- Updgrade version of 'mock' installed to version 3.0.5, the last version which supports Python 2. This fixes a bug where the file object returned from `mock_open()` was not iterable (see https://bugs.python.org/issue32933)
- Add support for Python 3 setuptools and pytest in sonic-slave-buster environment
- Add tests for `device_info.get_machine_info()` and `device_info.get_platform()` functions
- Also add a .gitignore in the root of the sonic-py-common directory, move all related ignores from main .gitignore file, and add ignores for files and dirs generated by pytest-cov

[arista/aboot]: Zero out 1st MB before repartitioning (#5220)
The first partition starting point was changed to be 1M as part of this
commit: 6ba2f97f1e. On systems that are misaligned before conversion
(partition start is the first sector), the relica partition that is
left in the first MB can cause problems in Aboot and result in corruption
of the filesystem on the new aligned partition.

Zeroing this old relica makes sure that there is nothing left of the old
partition lying around. There won't be any risk of having Aboot corrupt
the new filesystem because of the old relica.

[sonic-host-service]: Add SONiC Host Services infrastructure (#4840)
- Why I did it

When SONiC is configured with the management framework and/or telemetry services, the applications running inside those containers need to access some functionality on the host system. The following is a non-exhaustive list of such functionality:

Image management
Configuration save and load
ZTP enable/disable and status
Show tech support
- How I did it

The host service is a Python process that listens for requests via D-Bus. It will then service those requests and send a response back to the requestor.

This PR only introduces the host service infrastructure. Applications that need access to the host services must add applets that will register on D-Bus endpoints to service the appropriate functionality.

- How to verify it

- Description for the changelog

Add SONiC Host Service for container to execute select commands in host

[docker-radv] Fix startup issues (#5230)
**- Why I did it**

PR https://github.com/Azure/sonic-buildimage/pull/4599 introduced two bugs in the startup of the router advertiser container:

1. References to the `wait_for_intf.sh` script were changed to `wait_for_link.sh`, but the actual script was not renamed
2. The `ipv6_found` Jinja2 variable added to the supervisor config file goes out of scope before it is read.

**- How I did it**
1. Rename the `wait_for_intf.sh` script to `wait_for_link.sh`
2. Use the Jinja2 "namespace" construct to fix the scope issue

**- How to verify it**

Ensure all processes in the radv container start properly under the correct conditions (i.e., whether or not there is at least one VLAN with an IPv6 address assigned).
