qa/suites/orch: add a new smb service cephadm sub-suite and test

Start a new subdir under cephadm suite for the new smb service
that cephadm can deploy. Add one new test that checks that a
smb service with domain membership can be deployed and connect
to it with smbclient from the samba client container image.
