 * @title   BoosterOwnerLite

 * @notice  Immutable booster owner that requires all pools to be shutdown before shutting down the entire convex system
 * @dev     A timelock is required if forcing a shutdown if there is a bugged pool that can not be withdrawn from.
 *          Allow arbitrary calls to other contracts, but limit how calls are made to Booster.
 *          A lite version of the original Booster for use on sidechains
