Add support for Retry= and RetryDelay= to Podman Quadlet.

[jankaluza]

This commit adds new Retry= and RetryDelay= options to quadlet.go which result in --retry and --retry-delay usage in podman run command.

This allows configuring the retry logic in .container systemd files.

Fixes: #25109

Does this PR introduce a user-facing change?

The Retry= and RetryDelay= options are now supported in the systemd .container files.

image and build units also should accept these options for consistency.

$ podman build --help | grep retry
      --retry int                                    number of times to retry in case of failure when performing push/pull (default 3)
      --retry-delay string                           delay between retries in case of push/pull failures
$ podman pull --help | grep retry
      --retry uint                   number of times to retry in case of failure when performing pull (default 3)
      --retry-delay string           delay between retries in case of pull failures

Thanks, that's a good point. I've added them in the latest update :-).

But checking that PR once more, I did not add documentation for them, will add it :-).
