> In Blueprint deployments it is supported to specify a host predicate and host
> count to control which hosts and how many hosts will automatically join the
> host group. In case later is decided that less hosts to be used for the host
> group thus only a few hosts (less than the original host count) will be
> provisioned currently there is no way to remove pending host requests
> (created for hosts never joined to the cluster) so actually reducing host
> count for a host group.
