* Created the new tools/anvil-provision-server tool which will handle provisioning new servers, as well as having an interactive menu system to provision servers from the command line.
* Created Cluster->assemble_storage_groups() and moved the logic to auto-assemble groups out of Get->available_resources(). * Created Cluster->get_anvil_name() that will return an Anvil! name for a given anvil_uuid, or the name of the Anvil! if the host is a member of an Anvil!. * Updated Cluster->get_anvil_uuid() to return the 'anvil_uuid' if passed a specific 'anvil_name'. * Updated Jobs->clear() to use 'switches::job-uuid' when a job_uuid is not passed but the value exists in 'switches::job-uuid'.
