This ended up causing more issues than it solved, reverting.

15.08, but this keeps track of allocated cpus as well as usable cpus:
meaning if a user requests --hint=nomultithread they are allocated cpus
that aren't usable since they requested to only use the 1st thread on
each core.

Really do commit d388dd67 a different way to get the same info and
be able to lay out tasks correctly when --hint=nomultithread.

tests on a 4 core 8 thread system are

   1 snowflake0 - MASK:0x2
   2 snowflake0 - MASK:0x4
   3 snowflake0 - MASK:0x8
   4 snowflake1 - MASK:0x1
   5 snowflake1 - MASK:0x2

and

srun -n10 -N5 --hint=nomultithread --exclusive whereami | sort -h
srun: cpu count 10

This is a re-factor of commit e5635a76 related to bug 1148 to handle
the cases where a job could run, but an error was given when selecting
the nodes.

condition when adding a QOS and planning on using it right away when the
controller is busy with previous requests.

Before it wasn't taking into account if the user was requesting per node
memory or the job was told it needed to use less than the node allowed.
