Simply getting a subresource should return its actions

[abellotti]

GET /api/vms/5 as well as GET /api/providers/1/vms/5 should both return the vms/5 actions.

Currently the latter signature does not and is causing the manageiq-api-client to not allow vms operations on subresources.

Needed for: ManageIQ/manageiq-api-client#61

Actually, I am not sure about this. This was never the case in earlier release.

I think the API clients could simply recenter the requests at the resource's primary URL, so we'd rely on actions listed in GET /api/vms/5. What this would allow deeply nested QueryRelation::Queryable, and if done properly allow fetching subcollections at each level.

miq.providers.where(:name => "test-provider).first.vms.where(:name => "test-vm").first.snapshots.count

In theory :)

Closing this for now.
