bsc: Add testscase & infra to validate Osmux support BTS<->BSC

Browse Source 
New TC_assignment_osmux_bts is added which tests Osmux used only
BTS<->BSC.
Existing TC_assignment_osmux is renamed to TC_assignment_osmux_cn,
and a new TC_assignment_osmux is added which tests using Osmux on both
sides (towards BTS and CN).
