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.
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.
Add a master switch so that the sync/async mode can be configured.
Example usage of the switch:
1. Configure mode while building an image
`make ENABLE_SYNCHRONOUS_MODE=y <target>`
2. Configure when the device is running
Change CONFIG_DB with `sonic-cfggen -a '{"DEVICE_METADATA":{"localhost": {"synchronous_mode": "enable"}}}' --write-to-db`
Restart swss with `systemctl restart swss`

- Adds test case for port breakout CLI
- Explicitly sets admin status of all the VS interfaces to down to be compatible with SWSS test cases, specifically vnet tests and sflow tests

Swap order of orchagent and portsyncd in start.sh and fix priorities
Many docker virtual switch tests are failing at the moment because orchagent never finishes initializing. After doing some searching I figured out that Ethernet24 is never published to State DB, which is reminiscent of #4821

Applications running in the host OS can read the platform identifier from /host/machine.conf. When loading configuration, sonic-config-engine *needs* to read the platform identifier from machine.conf, as it it responsible for populating the value in Config DB.
When an application is running inside a Docker container, the machine.conf file is not accessible, as the /host directory is not mounted. So we need to retrieve the platform identifier from Config DB if get_platform() is called from inside a Docker
container. However, we can't simply check that we're running in a Docker container because the host OS of the SONiC virtual switch is running inside a Docker container. So I refactored `get_platform()` to:
1. Read from the `PLATFORM` environment variable if it exists (which is defined in a virtual switch Docker container)
2. Read from machine.conf if possible (works in the host OS of a standard SONiC image, critical for sonic-config-engine at boot)
3. Read the value from Config DB (needed for Docker containers running in SONiC, as machine.conf is not accessible to them)
- Also fix typo in daemon_base.py
- Also changes to align `get_hwsku()` with `get_platform()`
- Created the VS setup to test DPB functionality
- Created "platform.json" for VS docker
- Added test case for Breakout CLI

As part of consolidating all common Python-based functionality into the new sonic-py-common package, this pull request:
1. Redirects all Python applications/scripts in sonic-buildimage repo which previously imported sonic_device_util or sonic_daemon_base to instead import sonic-py-common, which was added in https://github.com/Azure/sonic-buildimage/pull/5003
2. Replaces all calls to `sonic_device_util.get_platform_info()` to instead call `sonic_py_common.get_platform()` and removes any calls to `sonic_device_util.get_machine_info()` which are no longer necessary (i.e., those which were only used to pass the results to `sonic_device_util.get_platform_info()`.
3. Removes unused imports to the now-deprecated sonic-daemon-base package and sonic_device_util.py module
This is the next step toward resolving https://github.com/Azure/sonic-buildimage/issues/4999
Also reverted my previous change in which device_info.get_platform() would first try obtaining the platform ID string from Config DB and fall back to gathering it from machine.conf upon failure because this function is called by sonic-cfggen before the data is in the DB, in which case, the db_connect() call will hang indefinitely, which was not the behavior I expected. As of now, the function will always reference machine.conf.
virtual-chassis test uses multiple vs instances to simulate a
modular switch and a redis-chassis service is required to run on
the vs instance that represents a supervisor card.
This change allows vs docker start redis-chassis service according
to external config file.
**- Why I did it**
To support virtual-chassis setup, so that we can test distributed forwarding feature in virtual sonic environment, see `Distributed forwarding in a VOQ architecture HLD` pull request at https://github.com/Azure/SONiC/pull/622
**- How I did it**
The sonic-vs start.sh is enhanced to start new redis_chassis service if external chassis config file found. The config file doesn't exist in current vs environment, start.sh will behave like before.
**- How to verify it**
The swss/test still pass. The chassis_db service is verified in virtual-chassis topology and tests which are in following PRs.

* Restore neighbor table to kernel during system warm-reboot
Added a service: "restore_neighbors" to restore neighbor table into
kernel during system warm reboot. The service is started by supervisord
in swss docker when the docker is started.
In case system warm reboot is enabled, it will try to restore the neighbor
table from appDB into kernel through netlink API calls and update the neighbor
table by sending arp/ns requests to all neighbor entries, then it sets the
stateDB flag for neighsyncd to continue the reconciliation process.

* Fix potential blackholing/looping traffic and refresh ipv6 neighbor to avoid CPU hit
In case ipv6 global addresses were configured on L3 interfaces and used for peering,
and routing protocol was using link-local addresses on the same interfaces as prefered nexthops,
the link-local addresses could be aged out after a while due to no activities towards the link-local
addresses themselves. And when we receive new routes with the link-local nexthops, SONiC won't insert
them to the HW, and thus cause looping or blackholing traffic.
Global ipv6 addresses on L3 interfaces between switches are refreshed by BGP keeplive and other messages.
On server facing side, traffic may hit fowarding plane only, and no refresh for the ipv6 neighbor entries regularly.
This could age-out the linux kernel ipv6 neighbor entries, and HW neighbor table entries could be removed,
and thus traffic going to those neighbors would hit CPU, and cause traffic drop and temperary CPU high load.
Also, if link-local addresses were not learned, we may not get them at all later.
It is intended to fix all above issues.
Changes:
Add ndisc6 package in swss docker and use it for ipv6 ndp ping to update the neighbors' state on Vlan interfaces
Change the default ipv6 neighbor reachable timer to 30mins
Add periodical ipv6 multicast ping to ff02::11 to get/refresh link-local neighbor info.

Add PORTCHANNEL_INTERFACE interface for ipv6 multicast ping
format issue
* Combine regular L3 interface and portchannel interface for looping
* Add ndisc6 package to vs docker
* [docker-base] Instruct apt-get to NOT install 'recommended' or 'suggested' packages
