Implement preemption for system jobs. 
This commit implements an allocation selection algorithm for finding
allocations to preempt. It currently special cases network resource asks
from others (cpu/memory/disk/iops).

Alex Dadgar 3ba62efd5e Failed/paused deployments do not block migrations 
This PR changes behavior of the scheduler such that a task group with a
deployment that is failed or paused will not cause the scheduler to skip
migrations.

The reason for this change is that it causes a bad UX when draining
nodes with allocations that are part of a failed/paused deployment.
These operations should not be coupled in any way and this remedies
that.

Prior behavior was still correct, but required either jobs to
transistion to a healthy state or for the node to hit its drain
deadline.

This PR restores older behavior of detecting successful batch
allocations (04d86ffd1006fde9dfb2ca8c1237fe60b995b0e3). This has the
side effect that we correctly filter desired status stop but not
successful batch allocations and create their replacements.

Alex Dadgar 3904bde9a3 Fix batch handling of complete allocs/node drains 
This PR fixes:
* An issue in which a node-drain that contains a complete batch alloc
would cause a replacement
* An issue in which allocations with the same name during a scale
down/stop event wouldn't be properly stopped.
* An issue in which batch allocations from previous job versions may not
have been stopped properly.

Alex Dadgar 27256ebcc6 Placing allocs counts towards placement limit 
This PR makes placing new allocations count towards the limit. We do not
restrict how many new placements are made by the limit but we still
count towards the limit. This has the nice affect that if you have a
group with count = 5 and max_parallel = 1 but only 3 allocs exist for it
and a change is made, you will create 2 more at the new version but not
destroy one, taking you down to two running as you would have
previously.

Alex Dadgar 2650bb1d12 Distinct Property supports arbitrary limit 
This PR enhances the distinct_property constraint such that a limit can
be specified in the RTarget/value parameter. This allows constraints
such as:

```
constraint {
  distinct_property = "${meta.rack}"
  value = "2"
}
```

This restricts any given rack from running more than 2 allocations from
the task group.

Alex Dadgar 248315a2d9 Handle destructive changes before placements 
This PR updates the generic scheduler to handle destructive changes
before handling placements. This is important because the destructive
change may be due to a lowering of resources. If this is the case, the
handling of the destructive changes first may make it possible for the
placement to happen.

To reason about this imagine there is one node with CPU = 500.

If the group originally had:
* `count = 1`
* `cpu = 400`

And then the job was updated such that the group had:
* `count = 4`
* `cpu = 120`

If the original alloc isn't discounted first, nothing would be able to
place.
