make diffSystemAllocsForNode aware of eligibility
...
diffSystemAllocs -> diffSystemAllocsForNode, this function is only used
for diffing system allocations, but lacked awareness of eligible
nodes and the node ID that the allocation was going to be placed.
This change now ignores a change if its existing allocation is on an
ineligible node. For a new allocation, it also checks tainted and
ineligible nodes in the same function instead of nil-ing out the diff
after computation in diffSystemAllocs

Return FailedTGAlloc metric instead of no node err
...
If an existing system allocation is running and the node its running on
is marked as ineligible, subsequent plan/applys return an RPC error
instead of a more helpful plan result.
This change logs the error, and appends a failedTGAlloc for the
placement.

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.

This commit implements an allocation selection algorithm for finding
