Submit job via bash

[maddenp-cu]

Synopsis

JobScheduler.submit_job runs set -o pipefail in its subprocess command to ensure that failure of the primary command (and not tee, which the primary command's output is piped to) causes the subprocess to fail. This command is supported by bash, but not by other shells, and Python defaults to using /bin/sh, which may or may not be bash.

Add support to run_shell_cmd for specifying the interpreter, and have submit_job specify bash, via a which call to find it on PATH.
