[virtualswitch]: build docker-sonic-vs docker based on SAI virtual switch

[lguohan]

- What I did
Build docker-sonic-linux docker based on virtual switch

- How I did it
add linux platform to build docker-sonic-linux docker which is based on SAI virtual switch.

Will later add test in sonic-swss to use this virtual switch for testing.

- How to verify it
make configure PLATFORM=linux
make
docker load < target/docker-sonic-linux.gz
docker run --privileged --network container:sw -d --rm --name tt docker-sonic-linux
docker exec -it tt bash

lgh@lgh-issaquah:/data/sonic/sonic-buildimage$ docker exec -it tt bash

--as-root -T [](start = 69, length = 12)

I could not find the usage for the 2 parameters. I am not clear the problem trying to solve. Could you clarify?

man dpkg-buildpackage

 3. If  a  specific  target has been selected with the -T or --target option, it calls that target and stops here. Otherwise it runs the preclean hook and calls fakeroot debian/rules clean to clean the build-tree (unless -nc is special field).


       --as-root
              Only meaningful together with --target (since dpkg 1.15.0).  Requires that the target be run with root rights.

this is needed because we need to build a special target for syncd-vs.

ideally, we can seperate the vslib completely from sairedis repo, then we can first build vslib and the install it and then build syncd. but, it is not an option right now.

Thanks!

docker-sonic-linux [](start = 50, length = 18)

Call it docker-virtual-switch?

[lguohan]

changed to docker-sonic-vs

I need the sonic since this is the docker image that contains all sonic components
