[docker-sonic-vs]Added support for Mellanox-SN2700 based SKU for docker-sonic-vs (#9044)

Browse Source 
Added support for Mellanox-SN2700 based SKU for docker-sonic-vs and to differentiate platform based on hw-sku rather than on fake_platform in VS.
Currently SAI VS library uses hwsku based SAI profile to differentiate and mock different platform implementations. The same functionality in swss is achieved using a fake_platform env variable.
Using a fake_platform has some drawbacks that the vs container appears to still use a different vendor hw-sku

env
PLATFORM=x86_64-kvm_x86_64-r0
HOSTNAME=dd21a1637723
PWD=/
HOME=/root
TERM=xterm
HWSKU=Force10-S6000
SHLVL=1
fake_platform=mellanox
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
DEBIAN_FRONTEND=noninteractive
_=/usr/bin/env

In order to unify the approach at both swss and vs SAI and to be uniform throughout this PR introduces the approach of using hw-sku to differentiate different platforms. This requires support for Mellanox-SN2700 HWSKU for Mellanox platform which is also addressed by this PR.
