Adds the NeutronTunnelIdRanges and NeutronVniRanges parameters

This adds the NeutronTunnelIdRanges and NeutronVniRanges parameters
which govern the GRE or VXLAN tunnel IDs (respectively) that are to
be made available for overcloud tenant networks.

These both default to "1:1000," to retain the current behaviour.
They are propagated to the hiera data for puppet deploys and there
is a separate change to support passing these into the config via
the neutron tripleo-image-element at

https://review.openstack.org/#/c/199592/
