Doing some very bad cleanups for a merge in here like renaming a few fields (like the old column names) + `ByondCommand` + Removing deprecated API fields.
- Added MinimumLength to several existing and new
StringLengthAttributes.
- Refactored permissions off User model to new PermissionSet model.
- Added UserGroups, which contain their own PermissionSet. A user can
have either a UserGroup or dedicated PermissionSet.
- Added UserGroupController and client for handling groups.
- Renamed InstanceUser to InstancePermissionSet and associated it with
PermissionSets instead of Users.
- Inject active permission sets into AuthenticationContext.
- Sanitize away top level child properties of client request bodies
(hopefully).
- Added groups integration tests. Main test now runs in a group context.
- Added migrations with hand-written transition SQL.
- Resetting the admin user disassociates them from any groups.
Fuck this huge commit
