Update dockers with platform & SONiC version as part of name/tag. (#4337)

* Include platform info in name.
Get SONiC Version as parameter and use
Make additional tag as optional.
Avoid repetitions by using function.

* Per review comments, make SONIC_VERSION optional and added some comments.

* 1) Added additional params are optional
2) Handle DOCKER_IMAGE_TAG only if given
3) Use BUILD_NUMBER only if SONIC_VERSION not given
4) Tag with SONIC_VERSION if given.

Current behavior is not changed, unless SONIC_VERSION is given.

* Update per review comments
1) Added new args with options
2) Handle PORT possible being empty
3) Exhibit new behavior only if both version & platform are given.

* Drop redundant quotes
