[pve-devel] [PATCH manager v9 04/13] api: notification: add API for getting known metadata fields/values

[Lukas Wagner <l.wagner@proxmox.com>]

This new API route returns known notification metadata fields and
a list of known possible values. This will be used by the UI to
provide suggestions when adding/modifying match rules.
