Wait up to 20 seconds for gres.conf file before exiting.

This fixes some problems creating advanced reservations on heterogeneous systems, especially when core counts are specified in the reservation.
bug 1068

Make "srun --gres=none ..." work when executed without a job allocation
(i.e. srun creates the allocation plus the step). Previous logic would
try to create the job with a gres value of "none".

Fix for possible error if job has GRES, but the step explicitly requests a
GRES count of zero.

BlueGene/Q's runjob command requires a fully qualified pathname,
so only for that machine type, resolve the name in srun. This
partitially reverts commit 57efc873
but only for BGQ systems.

and only caused confusion since the cpu_bind options mostly refer to a
step we opted to only allow srun to set them in future versions.

Defer job step initiation of required GRES are in use by other steps rather
than immediately returning an error.

This isn't the case in the current code so this isn't as big of a deal.

This logic will also be removed in 14.11 so it become less of a deal as
well, but just to be safe we cover the base.
