Add support for audit/logger max retry and retry interval (#20402)

Current implementation retries forever until our
log buffer is full, and we start dropping events.

This PR allows you to set a value until we give
up on existing audit/logger batches to proceed to
process the new ones.

Bonus:
 - do not blow up buffers beyond batchSize value
 - do not leak the ticker if the worker returns
