Adds OpenDaylight resources for configuring cluster with docker

Adds OpenDaylight resources for configuring cluster with docker

In puppet-opendaylight configuring a cluster is done using an exec
calling an opendaylight script to configure the clustering file.  For
containerizing ODL, we cannot use exec as a puppet tag, therefore we
need to use a defined type to tag with.  This patch adds that defined
type to configure a cluster and a class to call it.  These will only be
used during containerized deploys and calls the same configuration
script used by puppet-odl.
