XCache was working stably at MWT2, AGLT2, Prague, BNL.

VP changes requested by Rod, Tadashi. 

Created XXX_VP_DISK for all 4 sites and "connected" them to ANALY queues at sites.

There are edge cases that need to be addressed: eg. original data copy exists only on tape. 

Quite a bit of traffic on all XCaches (> 3Gbps).

Now reporting all requests and replies to/from VPservice to ES so we can monitor it. Need to find a way to label jobs brokered against VP copies, now it's rather complex to identify them.

ServiceX work - new high performance transformer, work on kafka deployment, monitoring, performance characteristics.
