[bug#70542] Value in adding Shepherd requirements to file-systems entries?

Personally I prefer separating requirements and dependencies.
Dependencies adjusts the order of mounting file-systems /before/
provisioning 'file-systems, while requirements actually delays mounting
a file system until Shepherd services have started (by removing it as a
requirement for provisioning 'file-systems).

I think this distinction in behavior should be emphasized in the API and
manual.

An alternative to the requirement/requirements field is changing the
name to shepherd-requirement. That would be consistent with other
services and make the distinction between dependencies and requirements
unambiguous. (And sidestep the pluralization question.)

Happy to change to whatever the consensus is!
