Pull request overview

Updates the LogPoller run loop to avoid creating and selecting on the backup poller ticker when the backup poller is disabled, reducing unnecessary wakeups.

Changes:

• Create the backup poller ticker only when backupPollerBlockDelay > 0, otherwise leave the select channel nil.
• Replace case <-backupLogPollTicker.C with case <-backupLogPollCh so the select case is effectively disabled when the backup poller is off.
• Add an info log when the backup poller is disabled.
