Bug#20814396 PB2 IS SECRET ABOUT WHAT UNIT TESTS IT RUN

One can not see in PB2 test logs which unit tests have been run
and passed.

This patchs adds an option --unit-tests-report to mtr which
include the ctest report in mtr output.  It will also turn on unit
testing if not explicitly turned off with --no-unit-tests or
equivalent.

In manual runs one can always look in the ctest.log file in mtr
vardir.

--unit-tests are replaced with --unit-tests-report in files under
mysql-test/collections/ to activate report in PB2.
