Allowed service management during bootstrap to be skipped by defining…

… bootstrap_skip_services

During provisioning starting services can be problematic, for example in a
kickstart environment before first boot. Inability to start services can result
in the bootstrap procedure failing, resulting in loss of key information like
the hub a host was bootstrapped to. This change allows bootstrap to skip
managing services if the class bootstrap_skip_services is defined.
