Allow Flagging Jobs for Reservation Through Rules and/or Through a "bsub --plan" Option

Today, reservations in LSF are handled by the Top X jobs by ordered by Dynamic Priority using the variable MAX_JOB_RESERVE.  We believe that this is a shotgun approach.  We have millions of jobs a day that require 1 cores and less than 1GB of memory today, and they can always dispatch.  However, we have certain jobs that do any one of the following:

* Have topology that spans more than a single node
* Request more than X GB of memory
* Request more than on scheduling core
* Requests specific licenses or other scarce resources

It would be nice to either create a "Plan" by job, or by a set of resource requirements.  Let's say assuming we do the plan at the cluster level.

lsb.params
RESERVE_FOR=slots>1,mem>40000,blah>blah

lsb.queues
RESERVE_FOR=same_as_above

Still, we would always reserve for the top MAX_JOB_RESERVE variable accross the cluster, but we would not require the bsub option.  In the case a user specifies the bsub option, we should have the opportunity to unwind that in ESUB, or add via ESUB as well.
