Create the wifi_release test suite.

These tests are run against all release cadidates.  These tests
line up with a set of manual test cases.  Instead of having to
manually check all of these tests in the autotest front end, we can
now select this suite.

I have not made an update to suite_scheduler.ini since we need these
to be run against specific release candidates.  Sometimes those builds
are on mini branches and we need the results before 5 PM the same day
that the candidate is chosen by the TPMs.

BUG=None
TEST=None
