Subject: bst-here: Allow users to specify additional volumes to mount

One may want to mount additional volumes to preserve certain directories
or to share some data between the host and the container. Allow users to
do so by providing a `-v` option that passes its arguments to
corresponding `-v`/`--volume` option for `docker run` command.

Part of #378.
