When the container uses journald logging, we don't want to automatically use the same driver for its exec sessions. If we do we will pollute the journal (particularly in the case of healthchecks) with large amounts of undesired logs. Instead, force exec sessions logs to file for now; we can add a log-driver flag later (we'll probably want to add a `podman logs` command that reads exec session logs at the same time). As part of this, add support for the new 'none' logs driver in Conmon. It will be the default log driver for exec sessions, and can be optionally selected for containers. Great thanks to Joe Gooch (mrwizard@dok.org) for adding support to Conmon for a null log driver, and wiring it in here. Fixes #6555 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
