Merge branch 'amiranda/116-adhoc-storage-deployment-needs-to-be-refactored' into 'main'

Resolve "Adhoc storage deployment needs to be refactored"

This MR implements a generic mechanism for deploying adhoc storage
systems in `scord-ctl`. The mechanism allows users to define via
the `scord-ctl.conf` configuration file which scripts should be 
used to start and stop an adhoc storage system.

Closes #116
