[pbs-devel] [RFC proxmox{, -backup} 0/5] switch local storage usage titles based on datastore backend

[Christian Ebner]

This patches try to more clearly show to the user that the statistic shown
in the datastore summary and overview only show the local cache usage.

To achieve this, the first patches include the datastore backend type in both,
responses for the `datastore-usage` as well as `status` api endpoints, in order
to be able to adapt the shown information conditionally.

Based on the backend, the title for the disk usage and rrd chart are adapted,
the estimated full values are also not shown in case of local caches.

This is intended more as a stop gap until a more sophisticated dashboard and
statistics are implemented for S3 backends as tracked in [0].

Sending this as RFC as I am unsure if:
- it is acceptable to include the backend type in these api responses, as they
  are intended for dynamic status changes?
- there is a better/alternative way to get the backend type?
- it might make sense to simply not return usage statistics for the cache (e.g.
  returning 0 values only) and keep this api endpoints free to be reused for the
  S3 dashboard?
