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.

Track top k nodes by norm score rather than top k nodes per scorer 2018-09-04 16:10:11 -05:00
Preetha Appan 6ed527c636
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.
