SUSE: Add OpenStack cloud repository when bootstrapping the host

This is similar to I21ab8e13f25bb7a769dcf504fa6915303bc2feec. Even
though most of the bootstrap packages are provided by the distribution
mirrors, it's best if we add the OpenStack repository just in case
there are any OpenStack specific package updates.
