debugd: daemonize logstash containers

[burgerdev]

Context

There is a race condition between starting the logcollection pods and waiting for them to become ready. If the cmd.Start() is not fast enough to create the container, podman wait will error out because it does not know about the container.

Proposed change(s)

• Daemonize the logcollection containers and wait for the podman command to run through.
• Add a restart policy to ensure they keep running (or crash-looping).

Note that the logs of the podman containers either end up in OpenSearch (if everything is fine), or are not accessible (if logcollection is broken). Either way, the outcome is the same as before this change.
