* commit 'cb8d7f9693639da1691a24f651b0b966497ec507':
Hopefully fixed the casa5 path in bamboo
Switched all references to the old regression repo to the new casa-data-req locations
A data path was slightly off for the case that no req dir is found
CASA 5 was still looking at the regressions/unittests data. Fixed to look at casa-data-req
Changed casa6 to look at reference files in the casa-data-req/text repo. The reference files were also renamed to match the test case.
Changed casa6 data path to accomidate the bamboo structure
changed the merged test case name and removed duplicate test case
removed the old test from the CMake and unittest list files
Moved merge to casa6
Renamed test_listobs to test_req_task_listobs
merged req test into test_listobs
