* Added an example of fronting the playbook's integrated Traefik reverse-proxy with the existing Caddy container (not the `apt-get` or `yum` installed Caddy).  Helpful for folks who have an existing server with a Caddy container already serving multiple applications.

* Update examples/reverse-proxies/caddy2-in-container/README.md

* update http2 config due to deprecation

the previous way to let `http2` follow a `listen` was depracated, it
moved to `http2 on;`

* enable quic and http3

I hope the comments are somewhat understandable. if someone can describe
the `reuseport` part more concise, please do.

This reverts commit 9c01d875f3.

This is very confusing and messy.. but it's documented.
`ansible_become_*` variables actually take priority and override all `become_*`
variables set at the task level.

As such, using `ansible_become=true ansible_become_user=root` in
`inventory/hosts` causes issues because tasks that specify
`become: OTHER_USER` will be forced to run as `root` due to
`ansible_become_user`.

For some of these, the `ansible_` prefix does not seem to be needed,
but it's the canonical way to do things and it may become required in
newer Ansible versions.

Updated the 'nginx reverse-proxy fronting' documentation with a guide for Nginx Proxy Manager, as you can't use the pre-existing nginx matrix.conf

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2090

This paves the way for installing other roles into `roles/galaxy` using `ansible-galaxy`,
similar to how it's done in:

- https://github.com/spantaleev/gitea-docker-ansible-deploy
- https://github.com/spantaleev/nextcloud-docker-ansible-deploy

In the near future, we'll be removing a lot of the shared role code from here
and using upstream roles for it. Some of the core `matrix-*` roles have
already been extracted out into other reusable roles:

- https://github.com/devture/com.devture.ansible.role.postgres
- https://github.com/devture/com.devture.ansible.role.systemd_docker_base
- https://github.com/devture/com.devture.ansible.role.timesync
- https://github.com/devture/com.devture.ansible.role.vars_preserver
- https://github.com/devture/com.devture.ansible.role.playbook_runtime_messages
- https://github.com/devture/com.devture.ansible.role.playbook_help

We just need to migrate to those.

Doing this further simplifies examples/vars.yml.

We're trying to move away from implementation-specific variables,
hoping for a clean (implementation-neutral) examples/vars.yml file.

Doing this seems more reasonable and simpler.

- caddy v1 requires a path in the header directive
- msisd has been replaced in favour of ma1sd

Seems to have been added by mistake.

Mostly affects people who disable the integrated `matrix-nginx-proxy`.
