Access logs lifecycle

[PerGon]

Add controller.logs.lifecycle to the access-logs sidecar container template, matching the pattern already used by the controller and haproxy containers.

This allows configuring a preStop hook on the syslog sidecar — useful when the haproxy container also has a lifecycle rule to, for example, need a drain period before termination. Without this, the syslog container can exit before HAProxy finishes serving in-flight requests, causing those requests to go unlogged.

Thanks for the contribution!

There's already an ongoing update and tests to move log and external haproxy containers as native sidecars which makes the lifecycle configuration without a clear proposal.

It looks good anyway, since we already have distinct lifecycle configurations for controller and external haproxy, this one is easier to backport to older branches, and this could also be used for niche or very specific use cases even on native sidecar deployments.

It is missing however the update in the readme file, and since you're already updating the PR, I also pointed a nitpicking in the values update.

Thanks for the comments - I've addressed them :)

Cool to know about the move to native sidecar containers 💪
