Change subject: BSC_Tests: add OML tests for bts_setup_ramp
......................................................................
BSC_Tests: add OML tests for bts_setup_ramp
The current BSC_Tests are using osmo-bts-omldummy to keep OML out of the test
context.
Add a new test file and component for OML tests.
