Merge pull request #946 in CASA/casa from CAS-12323 to master
* commit '40c59322e78aa5992d088bfe623e281599bd5c9b':
First version of a subset of test_mstransform to run in serial. In my local Docker CentOS 6 the full test_mstransform suite takes 613.075s to run. The new test_mstransform_subset takes in the same Docker 404.812s and skips 67 tests. This is 65% of the full suite run time.
