manage discrete repo of workflows, share as volume

[bertsky]

The Monitor must have read access (soon also: write access) to the repository of workflow scripts. Currently they are deployed in the Manager container only.

Proposal: a dedicated path within the shared volume, optionally under git version control. Workflows are copied to the process directory prior to processing.

Additionally, I suggest introducing a workflow mount directory where users can place their workflow files (and also the required models?).

(and also the required models?).

That already exists (volume /models), but on the Controller (naturally).

Indeed, this should be a bind-mount, not a shared volume.
