[PATCH datacenter-manager] api: nodes: add explicit permission check for RRD data points endpoint

[Shan Shaji <s.shaji@proxmox.com>]

The /rrddata endpoint did not have the access parameter defined inside
the API macro. This resulted in a "403: permission check failed" error
in the UI even though the user was assigned the Administrator role on
the / ACL path. This issue was raised in the forum [0].

Fix this by adding the explicit permission check.
