Deprecates using exec workaround for ODL clustering

Previously we had used an exec defined in puppet-tripleo to do
clustering with OpenDaylight docker containers.  The clustering issue is
now fixed in puppet-opendaylight by:
https://git.opendaylight.org/gerrit/#/c/60491

So removing the custom function and class workaround.  Also,
'ha_node_index' is deprecated for configuring clustering with
puppet-opendaylight so that is also removed.
