staff discovery api
A common concern amongst the greater fediverse admin community is discovering who is responsible for maintaining and moderating a given instance.
This MR solves this for Pleroma by implementing an extension to the /api/v1/instance
API allowing for programmatic discovery of instance staff through the staff_accounts
field.
This is presently a Pleroma extension to the Mastodon API, but I intend to propose it upstream as well.
