Modify the semantics of CQD MAX_ESPS_PER_CPU_PER_OP to become a factor in
computing the max #ESPs per core. The #esps per node = CQD * cores per,
node and the total number of ESPs per cluster is #esps per node * #nodes.

The CQD now takes a real number.

The work consolidates all references to the CQD to three new methods
NADefaults::getNumOfESPsPerNode(), NADefaults::getNumOfESPsPerNodeInFloat()
and NADefaults::getTotalNumOfESPsInCluster().
