Introduce Fellowship into Collectives (#2186)

* Fellowship into Collectives * cargo.lock * tracks alias * allow to send Fellows origin over XCM * update todos, remove duplication of type * use Collectives location for Fellows body * alias for ranks constants * benchmarks * proxy for Fellowship * docs * correct copyright date * Apply suggestions from code review Co-authored-by: joe petrowski <25483142+joepetrowski@users.noreply.github.com> * rustfmt * remove council, update origins * renames * remove tech committee from promote origin * renames * doc nits * weights with new api * sane weights for pallet_scheduler * XCM tweaks for OpenGov (#2305) * updated xcm configs for collectives and statemint * remove xcm send from safe filter * remove prod_or_fast * remove empty line * drop redundant aggregation * remove match arm duplication --------- Co-authored-by: joe petrowski <25483142+joepetrowski@users.noreply.github.com>
