[enhancement] job_timeout in batch jobs

[MorphBonehunter]

It would be a good extension for the batch job system to define an max running time for the job.
For example if i define an periodic job which runs */15 i would like to have the ability to define an job_timeout (with no default) of "5m" after which the job gets killed and marked failed.
This prevents "hanging" scripts and in case of prohibit_overlap that the job isn't executed on the next schedule.

As mentioned in Gitter chat, the timeout binary in coreutils can do this inside the container if you need a fix right now.

timeout 5 /path/to/slow/command with options

@jippi thanks for your suggestion ( i doesn't realize in gitter because the mention is to someone else 😄 ) and i will check this.
However i think this could be an usefull addition to nomad, so i've decide to open this issue.

I agree having it native to Nomad would be nice :)
