This is the first implementation of CephX key rotation in Rook. Adds key rotation API from design PR 15915. Also add helper methods for rotating keys, determining when keys need to be rotated, and for generating CephX key statuses. These will be reusable for other Rook reconciles beyond object/RGW.
