Remove ThorCluster prop @slaves

Already absent from the xslt/xsd's, but still part of the environment xml
and generated by the wizard.
Remove from environment and calculate based on ThorSlaveProcess and
slavesPerNode.
Which avoids having to maintain (and potentially get wrong) number of slaves
in environment.

gh-1332 - Reduce dafilesrv inactive client logging

A connected inactive client (>12mins), was being checked every minute
to see if was still alive and if it was "Inactice client" messages for all
files from the client were being logged.
This can be excessive in some situations.

Still want to check per minute, but add extra timeout to control frequency
of warning

Implement a SHUFFLE activity and keyword

- New SHUFFLE keyword (provisional)
  SHUFFLE(ds, { grouping }, { sort }, options);
  Equivalent to
  UNGROUP(SORT(GROUP(ds, grouping, options), sort));

- Add options to
  * Translate SHUFFLE operations to equivalent if engines don't support it
  * Create SHUFFLE for the inputs to thor local joins if possible.
  * Use SHUFFLE instead of a SORT if that is possible.
  * Use shuffle to reorder join conditions if one side is already sorted
