Open source Preemption code
...
Nomad 0.12 OSS is to include preemption feature.
This commit moves the private code for managing preemption to OSS
repository.

Use debug logging for scheduler internals
...
We currently log an error if preemption is unable to find a suitable set of
allocations to preempt. This commit changes that to debug level since not finding
preemptable allocations is not an error condition.

scheduler: Add is_set/is_not_set constraints
...
This adds constraints for asserting that a given attribute or value
exists, or does not exist. This acts as a companion to =, or !=
operators, e.g:
```hcl
constraint {
attribute = "${attrs.type}"
operator = "!="
value = "database"
}
constraint {
attribute = "${attrs.type}"
operator = "is_set"
}
```

Fixes device scheduling unit tests

Also changes the logic for score when there is more than one task
requesting a device. Since inter task affinities are already normalized,
we take the average of the scores across tasks.

This commit implements an allocation selection algorithm for finding

from others (cpu/memory/disk/iops).
