Implement CLI/API feature showing actual hostnames where allocation runs.

[zoza1982]

Hi, this is a feature request.

Since killing a specific allocation which is part of the same job with multiple instances is not implemented yet (#2181) it would be good for purposes of chasing down that bad behaving allocation and killing it manually with kill -9 to add ability to both "nomad status " CLI and API to show the actual hostname where allocation runs along with other info like Node ID.

In the meantime I took a stab at a curl+jq script to make things a little easier:

#!/bin/bash
set -e

ids=$(curl -s localhost:4646/v1/allocations | jq  -r ".[] | select(.JobID==\"$1\") | .NodeID")
for id in $ids; do
    curl -s localhost:4646/v1/nodes | jq -r ".[] | select(.ID==\"$id\") | .Name"
done

Thanks! That will work in the meantime!

We merged a PR that should display Node Name for job status and alloc status commands. Closing this one.
