Support additional LabelsFinder parameters for group labels

See merge request gitlab-org/gitlab-ce!17447

Because epic index page includes also epics from subgroups
it's necessary to also get descendant group labels for filtering.

Allow CI/CD Jobs being grouped on version strings

See merge request gitlab-org/gitlab-ce!17455

In some situations (listing labels for epics) we want to
list only group ancestor labels, this is already supported
in LabelsFinder we just need to enable additional parameters.

Also `set_issuables_index` method now loads project labels only if
@project is set (which is not used for epic group labels).
