WP 13432 Connect LDAS and CDS via a new fiber link to support NGDD data access.

Dan Moraru, Jonathan Hanks,

Per WP 13432 Dan and I put a new link between LDAS and CDS in.  This is to support stream data via the ngdd tooling for IR1 and later.  What we ended up doing was to create a gateway box running vyos (a router OS) and using that as the gateway to the internal LDAS network that the NGDD servers live on.  I updated DNS so the servers resolve properly in the control room and have shown that I can pull data from NGDD.  The gateway box is runnong on the VM cluster, so it gains high availability and can be easily scaled up if we need to expand its capacity.
