Enable marking of coverage tests so that we can
allow some tests to fail without blocking the generation
of coverage data. This will later allow us to
fail the coverage job if other kinds of errors occur and
to capture which tests we believe are not running properly
with coverage enabled.

Allow FAIL and CRASH to avoid yellow, otherwise
if we added to regular CI run we'd have perma-yellow

Allow new tests to fail until we get a ci job added
to the main regression job so that comits don't break
coverage that have to be fixed later on.
