Correctly end mapping oversubscribed nodes round-robin byslot

cmr=v1.8.3:reviewer=rhc
Ensure the nodes get added to the job map on the remote nodes, add some debug to grpcomm daemon array construction
Protect debug printing on backend nodes
Don't explicitly add the hostname to the data fetch when we already cached a remote blob
Add a bunch of debug to help track down the problem, and eventually find another place where comparison of signatures was incorrectly performed - use the dss compare operation to be consistent and safe
Turn off the coll/ml component if --without-hwloc was given
