[stable/rabbit-ha] Added liveness probe period

[RaymondArias]

What this PR does / why we need it:

Enable liveness probe period for rabbit-ha nodes. The current liveness probe looks like it is cpu intensive, the idling pods consume ~500 millicores because of the liveness probe.

This allows for users to decide how frequently to run liveness probe and cutting down cpu usage drastically.

Which issue this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close that issue when PR gets merged): fixes #3855

Hi @RaymondArias. Thanks for your PR.

I'm waiting for a kubernetes 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.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
