Disable leader election, too much noise in log

[vincent-pli]

The interval is 2 sec, too much noise in the log of controller, and there is only one replicate, no need for leader election

Hi @vincent-pli. Thanks for your PR.

I'm waiting for a kcp-dev member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

This is not an extensive example where we are dealing with multiple replicas, disabling LE should be fine.
