Testsuite profile for Travis CI only

We should have a maven profile to be used for the testsuite runs on Travis CI only.
We happen to have intermittent/transient failures on Travis CI that are impossible to reproduce locally. While it's great that Travis flags those situations (most of the cases, there's indeed a problem, either in the code or more often in a test), in some cases isolating the culprit / reason for the failure is so hard that we might simply want to try disabling one/few tests and see if the builds gets back to stable state.
If we had a profile used by Travis CI only, we could exclude the tests only for Travis in such profile (waiting for it to be analyzed), while letting them still run locally, so that the test regression coverage is not affected too much.
