[pdm-devel] [PATCH datacenter-manager 1/2] fix #6901: api: add permission checks for PBS rrd endpoints

[Shan Shaji]

When a non-root user tried to view the RRD data of the PBS node or
datastores, even with Administrator privileges, the API was
returning a "403: permission check failed" error. This occured
because the access property was not defined inside the `api` macro.

To fix the issue, a resource level permission check was added.
Now if a user has atleast the `Resource.Audit` permission, then they
can access the RRD data of the node and datastores.
