Add a plugin to execute arbitrary commands when a build finishes

Browse source 
The plugin can be configured using one or more <runcommand> sections
in hydra.conf, e.g.

<runcommand>
  command = echo Build finished
</runcommand>

Optionally, the command can be executed for specific
projects/jobsets/jobs:

  job = patchelf:master:tarball

or

  job = patchelf:*:*

The default is *:*:*.

The command is executed with the environment variable $HYDRA_JSON
pointing to a JSON file containing info about the build, e.g.

    "stopTime": 1533137094,
    "timestamp": 1533136076
  }

So for example, the following command:

  command = echo Build $(jq -r .build $HYDRA_JSON) \($(jq -r .project $HYDRA_JSON):$(jq -r .jobset $HYDRA_JSON):$(jq -r .job $HYDRA_JSON)\) finished, metrics: $(jq -r '.metrics[].value' $HYDRA_JSON).

will print

  Build 3772978 (patchelf:master:tarball) finished, metrics: 20282 6664.
