HPCC-9784 - Fix workunit output limit regression

A regression introduced by HPCC-8743 (in 4.0), prevented the limits
on workunit results being checked. Normally an excessively
large (default 10MB) workunit result, results in an error.
Large results should be committed to disk.

Changes in HPCC-8743 inadvertently caused the limit to be turned off.

HPCC-9795 Roxie needs to figure out numChannels

Some hidden attributes that were calcluated by configmgr were not in the xsd,
or were marked as readonly there. configmgr no longer calculates them, making
it very hard to set up a new Roxie cluuster.
