recently added hotspot/test/applications significantly increases execution time of :hotspot_all test group, because of that this group is not longer a good choise for everyday usage for ensuring that a fix does not introduce regressions. since it's expected that hotspot_all contains all hotspot tests including application tests, we can not exlcude application tests from this group, so we need to introduce a new group to cover this usecase.

suggested name for this new group is hotspot_all_no_apps.

it also might make sense to create other groups using test execution time for classification: hotspot_fast, hotspot_medium, hotspot_slow.
