n/a

**Special notes for your reviewer**:

Before this change, if I created an ACR with name `colemicktest`, then the login server would be `colemicktest-microsoft.azurecr.io`. This code was concating to form `colemicktest.azurecr.io` which does not work.

The fix is to reach into RegistryProperties and read out the login server domain name directly.

Also, this should eliminate that existed when ACR gets to sovereign clouds.
