Add timeout support to run_cmd

When calling shell commands on a VM we have a default timeout
of 60 seconds (in the session functions designed to run remote
commands). However, some arnied_wrapper functions such as
`wait_for_run` (which calls `arnied_helper
--wait-for-program-timeout`) require a larger timeout, so we
need to be able to overwrite the default.
