/**
 * This command is for deploying all resources associated with a flexrep config. It combines CPF, flexrep configs
 * and targets, and optionally an HTTP server by reusing other commands. The intent is to support a configuration
 * for both a master and a replica in the same project. Most of the time you won't need this, in which case you
 * can just use DeployConfigsCommand and DeployTargetsCommand.
