- Document that create_domain_connection is unimplemented on Spacebar
- Add Discord connection type
- Change ConnectionType::array() into ConnectionType::vector() - returning a fixed size array is dubious, since it'll likely be expanded. Returning a vector is easier keep up to variable length
- Add ConnectionType::discord_vector() and ConnectionType::spacebar_vector() to return a vector ConnectionTypes available on the respective server backends
- add tests test_modify_user_profile, test_disable_user, test_get_user_note, test_set_user_note, test_get_user_affinities, test_get_guild_affinities, test_get_connections
Note: connections are hard to test, since they require secrets / an external service's account
