Instead of waiting for all jobs to clear out of the system, wait until
all jobs are completed. This helps so that you don't have to wait as
long for the cluster to be drain and or removed.

Clusters in the federation could be different rpc_versions so each
cluster needs to talk each other's language.

Routes request to origin cluster if it isn't running the job.

to give more flexibility.

if a federated job.

Move from slurm_send_recv_controller_rc_msg to
slurm_send_recv_controller_msg. This allows scontrol requeue to be
rerouted to the origin.

Report that "CPUs" plus "Boards" in node configuration invalid only if the
    CPUs value is not equal to the total thread count. In any case, the
    CPUs value is ignored, but it is also output by "slurmd -C".

fragmentation.

Bug 3756

Two jobs completing simultaneously leads to make_node_idle()
returning before it has a chance to decrement node_ptr->owner_job_cnt,
which can result in the node being "owned" by that user even
through no jobs are running on it.

Move the decrement block to the end at a fini label, and make sure
all return paths pass through it. While moving that add a guard
against node_ptr->owner_job_cnt underflowing.
