Description

Currently, the `groups` and `excludedGroups` work like:

( include1 OR include2 ... ) AND NOT ( exclude1 OR exclude2 OR ... )

This doesn't cover many usecases. For instance, if the groups overlap.
Example: user needs to run only EJB tests under security manager, while only some EJB tests can run under security manager.
In such case, this is needed:

( EJB AND SecurityManager )

The suggestion is to introduce two new params:

groupingMode = union|intersection
excludeGroupingMode = union|intersection

They would switch AND and OR behavior.
Union would be the default (preserving current behavior).

Would be implemented in a filter, see:
