core: Add a profile to exclude gluster tests
core: Add a profile to exclude gluster tests

Gluster tests are the main users of PowerMock, which forces the build to
fork its tests. This new optional profile (-Pdisable-gluster-tets)
allows runnign the build without gluster tests, which allows using
-Dengine.powermock.fork=once, to dramatically shorten the build time.
