Merge branch 'hub' into hub_fabric_deploy_needed
Fixes for fabric provisioning.

Remove 'deb_utils', as we are no longer using them.  Rename
'install_config' to 'config'.  Move some of the management commands
used as part of 'localwiki-manage setup_all' (e.g. 'init_db') into the
fabric provisioning code.
