> This jira will add {{ENTERING_MAINTENANCE}} and {{IN_MAINTENANCE}} to {{AdminStates}} and protobuf. It will also provide the basic functionality to transition DN into or out of maintenance state from DN's state machine's point of view. The actual admins support and block management will be covered by separate jiras.
