Convert run_cim_operations.py into an end2end testcase

Convert run_cim_operations.py into an end2end testcase.

This includes getting rid of the RegexpMixin class which is tied to unittest and at this point is only used by run_cim_operations.py.

For release 1.7.0, all we want to do is to get the indication tests from a container with open pegasus running, and not all of the other tests that are in the manual test cim_operations.py

Meanwhile we do most of what this script does in the end2end tests.
So this item is to remove the script (and maybe double check that).
