<oo-install>turning oo-install openshift.sh into a symlink
- add target file to sed calls missing target file
- actually make use of CONF_HOSTS_DOMAIN_KEYFILE if set
- pipe stderr along with stdout where appropriate
- use bash regex substitution instead of messing with IFS
- switch oo-mco call to use server identity instead of public_hostname
- when multiple nodes belong to a district, only verify profile on first
  and then call oo-admin-ctl-district once for all nodes in that
  district.
