Subject: [PATCH] [docker-orchagent][201911] Pass ASIC vendor information to
 swss docker as docker level environment variable (#8274)

#### Why I did it
Recently, the reserved buffer of admin-down ports is going to be reclaimed.
However, the way to do this differs among vendors.
We need to find a way to pass vendor information to swss docker.

#### How I did it
Fetch the ASIC vendor information when the docker is created and pass it to the docker as environment variable `ASIC_VENDOR`.
