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).

Use heap to store top K scoring nodes.
Scoring metadata is now aggregated by scorer type to make it easier
to parse when reading it in the CLI.

When a job is stopped but not purged, we should set the Queued count to
be zero.

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.

Fixes https://github.com/hashicorp/nomad/issues/3210

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.
