Alex Dadgar 1e3c3cb287 Deprecate IOPS 
IOPS have been modelled as a resource since Nomad 0.1 but has never
actually been detected and there is no plan in the short term to add
detection. This is because IOPS is a bit simplistic of a unit to define
the performance requirements from the underlying storage system. In its
current state it adds unnecessary confusion and can be removed without
impacting any users. This PR leaves IOPS defined at the jobspec parsing
level and in the api/ resources since these are the two public uses of
the field. These should be considered deprecated and only exist to allow
users to stop using them during the Nomad 0.9.x release. In the future,
there should be no expectation that the field will exist.

Fix preemption logic bug, need to group allocations by device first. 
This ensures that the set of allocations chosen for preemption all share
the same device where ID is <vendor/type/device>

Danielle Tomlinson 9c72dafc95 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"
}
```

Danielle Tomlinson e5c641daa9 scheduler: Allow comparisons of nil values 
This commit allows the ConstraintChecker to test values that do not exist.
This is useful when wanting to _exclude_ given nodes from executing a
job, for example, if you wanted to give canary nodes an attribute, and
not run critical services on them, you may specify something like the
below, but not want to tag all other nodes with the inverse.

```hcl
constraint {
  attribute = "${node.attr.canary}
  operator = "!="
  value = "1"
}
```

This also requires all constraint checkers to allow for nil target
values, as they will no longer be short circuited by resolving a target.

Alex Dadgar 6d8bb3a7bd Duplicate blocked evals cancelling improved 
The old logic for cancelling duplicate blocked evaluations by job id had
the issue where the newer evaluation could have additional node classes
that it is (in)eligible for that we would not capture. This could make
it such that cluster state could change such that the job would make
progress but no evaluation was unblocked.

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.
