[Bug 2139385] [NEW] Update Ceph to new 20.2.0 (Tentacle) version

[Luciano Lo Giudice]

Public bug reported:

[Impact]

The update contains the following package updates:
https://ceph.io/en/news/blog/2025/v20-2-0-tentacle-released/

Key differences from upstream:
- UADK is not used in ARM64 as it requires checking out a repository during
  build time.

[Test Case]

This SRU will run all functional tests with the packages in 'proposed'
for every Ceph charm maintained by Canonical's Ceph team, so that
there's a higher chance of catching bugs associated with any Ceph
component.

The charms for which the functional tests will be run are: ceph-mon, ceph-osd,
ceph-radosgw, ceph-proxy, ceph-nfs, ceph-nvme, ceph-fs and ceph-rbd-mirror.

[Regression Potential]

Ceph is a critical package as it underpins large scale data storage and
integrity checking, and care must be taken to not introduce any data
loss regressions. ceph also is a common backing store for OpenStack
virtual machines through ceph-rbd, and care must be taken to not break
any API or ABI compatibility with current OpenStack releases.

In order to mitigate the regression potential, the results of the
aforementioned tests will be attached to this bug.
