Disable live-RPC queries under split query

parallelisation. For the 2.7 release, we reset these back to masterd,
hoping to revert them by the time 2.8 is ready.

There are a number of queries that I've left pointing to confd, as
they are non-RPC:

- node fields query
- node static fields query (and added a note in one case where it
  could become a problem)

All the other converted queries (job listing, group queries, tags,
cluster config) remain pointing to confd, as they don't use RPC.
