Can't suppress BOOST_TEST_MESSAGE output without suppressing TEST SUITE level

My tests use a lot of BOOST_TEST_MESSAGE calls to generate test trace. Unfortunately, this completely bloats XML output I use to integrate boost and Jenkins, since every message is appended to the xml file. If I reduce the log level, then there is no information about individual test cases in the XML file.

I should be able to use boost test messages for tracing and still obtain a compact test summary in xml when needed.
Adding every message to xml output is in most cases useless for me.

Possible fix:
Introduce BOOST_TRACE_MESSAGE or move MESSAGE level a few levels up.
