The `enable extras on centos` task just doesn't work when using the
variable ceph_docker_enable_centos_extra_repo to true.
fatal: [xxx]; FAILED! => {"changed": false, "msg": "Parameter

When using a http(s) proxy with either docker or podman we can rely on
the HTTP_PROXY, HTTPS_PROXY and NO_PROXY environment variables.
But with ansible, even if those variables are defined in a source file
then they aren't loaded during the container pull/login tasks.
This implements the http(s) proxy support with docker/podman.
Both implementations are different:
1/ docker doesn't rely en the environment variables with the CLI.
Thos are needed by the docker daemon via systemd.
2/ podman uses the environment variables so we need to add them to
the login/pull tasks.

When using TLS on the ceph dashboard or grafana services, we can provide
the TLS certificate and key.
Those files should be present on the ansible controller and they will be
copyied to the right node(s).
In some situation, the TLS certificate and key could be already present
on the target node and not on the ansible controller.
For this scenario, we just need to copy the files locally (on each remote
host).
