Add --nodes configs used by rdophase2

RDO Phase 2 has been running with these 3 configs
for a very long time.  They allow for running on
64 GB virthosts, as well as our virt-ha configuration
which is 40 core, 192GB.

This commit moves these upstream where they should
live, vs. carrying internally.
