Bug #11766640 (59789) Hook the invocation of unit tests in MTR.

Added code to call 'ctest' if the needed cmake file is present
Will do so unless tests/suited named on mtr command line
Also add option to turn on/off
Will be made to look like a test 'unit-test' which counts towards total
Extracts summary report and any test failures from ctest output
Addendum: added override to turn off in PB, add back in selected invocations
