dont update localbuild resource status when shutting down

[nimakaviani]

updating the resource when shutting down can create a race against a closed context which would throw the following undesirable error.

The PR checks whether we are shutting down before trying to update the localbuild resource. The assumption is that the necessary update to the status should have already happened.

I also think showing an error message for the missing cnoe.io/last-observed-cli-start-time annotation is confusing and misleading. Why I added another commit to prevent the reconciler from shutting down but also logging what we would otherwise see as an error message, as a logger.Info message
