Add flag to cmd for dynamic services
When cmd is called with the -w flag, it will call ServiceManager::waitForService instead of checkService. This will make dynamic services start and block until they are ready for use.
Bug: 149526916
Test: atest ApexRollbackTests (with and without this flag applied within for dynamic apexd)
