Zac Dover 3043aaaa8a doc/cephadm: add podman version note to install
This PR adds a note to the cephadm installation
guide that informs users that only podman version
2.0.0 and higher work with Ceph, with the
exception of podman version 2.2.1, which does
not work with Ceph. There is also a note regarding
kubic stable 3.0.1 working, but only with newer
kernels.

Compatibility with Podman Versions
----------------------------------
Podman and Ceph have different end-of-life strategies that
might make it challenging to find compatible Podman and Ceph
versions
Those versions are expected to work:
+-----------+---------------------------------------+
| Ceph | Podman |
+-----------+-------+-------+-------+-------+-------+
| | 1.9 | 2.0 | 2.1 | 2.2 | 3.0 |
+===========+=======+=======+=======+=======+=======+
| <= 15.2.5 | True | False | False | False | False |
+-----------+-------+-------+-------+-------+-------+
| >= 15.2.6 | True | True | True | False | False |
+-----------+-------+-------+-------+-------+-------+
| >= 16.2.1 | False | True | True | False | True |
+-----------+-------+-------+-------+-------+-------+
.. warning::
Only podman versions that are 2.0.0 and higher work with Ceph Pacific, with the exception of podman version 2.2.1, which does not work with Ceph Pacific. kubic stable is known to work with Ceph Pacific, but it must be run with a newer kernel.

Stability
---------
Cephadm is actively in development. Please be aware that some
functionality is still rough around the edges. Especially the
following components are working with cephadm, but the
documentation is not as complete as we would like, and there may be some
changes in the near future:
- RGW
Cephadm support for the following features is still under development and may see breaking
changes in future releases:
- Ingress
- Cephadm exporter daemon
- cephfs-mirror
In case you encounter issues, see also :ref:`cephadm-pause`.
