[PATCH ceph master/ceph squid/manager v4 0/7] Fix #6816: Prevent ceph-exporter Daemon from Crashing on Startup

["Max R. Carrara" <m.carrara@proxmox.com>]

Fix #6816: Prevent ceph-exporter Daemon from Crashing on Startup - v4
=====================================================================

tl;dr: Stop ceph-exporter.service from ending up in a crash loop by
handing it a custom keyring file and setting its group to `www-data`,
similar to what we did for ceph-crash.service [0] before.

v2 contains the entire description; see below for a link.

Changes Since v3
----------------

- Rebase the patches
- Change the PVE version in the debian/postinst changes (patch #03)
  to 9.2.4
- Add patch for Ceph Squid (patch #07)

Tested this for both Ceph Tentacle and Ceph Squid, but a quick smoke test here
would be much appreciated nevertheless.
