Background

The motivating use case is adding a --volume argument to modify the list of trusted certificate authorities trusted by Crunch jobs running in containers. This makes it possible to use a self-signed certificate for the API server, without having to customize the docker images being used.

Proposed feature

If an environment variable CRUNCH_JOB_DOCKER_RUN_ARGS is added to the crunch-dispatch run script, this should be propagated to crunch-job much like CRUNCH_JOB_DOCKER_BIN is now. Crunch-job should include this every time it uses docker run.
