ISPN-3964 Move unstable tests to different group * No tests are disabled. Unstable (random failing) tests should be marked with group 'unstable'. This can be applied to a class or a method. * Added profile test-unstable (-Ptest-unstable) to run only the 'unstable' group. * Enabled all stress,profiling,manual tests since they do not run automatically. * Removed not implemented tests.
