[Swift-devel] more on # of coasters workers vs actual requested on ranger

aha.

on Ranger the count clause , refers to the number of cpus hence when
coasters is requesting for count=4 it only needs 1 node.  if we want
to do a workersPerNode=16 then we should manually specify host_count=4
instead of count=4.  or just use workersPerNode=1

i'll do more rsl exploration and probably play with the coaster's
generation of GRAM2 requests.
