Add epics to project import/export

ImportExport::GroupProjectObjectBuilder tries to find existing one on
the Group level, and falls back to creating one if not found.

Use POST for session disable endpoints (signout & admin mode disable)

See merge request gitlab-org/gitlab!22113

User signout and admin mode disable use now POST instead of GET

The feature flag being `single_mr_diff_view`

When the backend for this feature flag was implemented,
everything was stubbed out to be false so it would pass.

The frontend work to integrate it has now flipped that, and all
the stubs should be removed.

This change modifies the actions and mutations
to handle only a single diff style (either inline or
parallel) and properly merge that with existing
files already in state (if any).
