[pbs-devel] [PATCH proxmox/proxmox-backup] add metrics server capability

[Dominik Csapak]

this series adds support for exporting metrics data to external
metric servers.

for now this includes only data we gather for RRD, though it should
not be hard to extend that functionality

also only influxdb (udp/http(s)) is currently supported, but it should
also not be too hard to include more options here

i did not include gui/cli patches yet, as i find the
proxmox-backup-manager options are already too much and i waited for
the gui for some feedback.

for testing, the metric servers can be added either by
calling 'proxmox-backup debug api ...' or by manually editing the
file

a bit unrelated: i moved the 'disk_usage' method to proxmox-sys
(fits better there, and we want to use that from other things too)

ofc, proxmox-backup depends on bumped versions of the proxmox-* crates

proxmox:

Dominik Csapak (3):
  proxmox-sys: make some structs serializable
  proxmox-sys: add DiskUsage struct and helper
  proxmox-metrics: implement metrics server client code
