ENH: adjust infoSwitch to report host subscription (related to #531)

• this compact form shows the subscription per host in the unsorted mpi order

  nProcs : 18
  Hosts  :
  (
      (node1 6)
      (node2 8)
      (node3 4)
  )

  This provides a succinct overview of which hosts have been subscribed or oversubscribed.

• The longer list of "slave.pid" ... remains available on the InfoSwitch 'writeHosts'

@Prashant / @Mattijs - see if there are any tweaks still needed.

One further idea might be to allow more items per line.

I wouldn't - people might parse the format.

• did you adapt foamCheckJobs/foamPrintJobs (if these still exist?)

This output change only affects the argList output. The jobInfo slaves will still have the long form.

The default slave printing seems to have changed to be the collated version. Desired?

Yes I think that this is desirable. Collated now corresponds to level 1 information (doesn't flood the output) and level 2 (full output) is still available for debugging.
