#11652 fix a data corruption bug when restarting etcd,but the old consistent index implementation is not elegant to call.
#11699 refactor consistent index to make the code look more concise and elegant.
#11670 add log when etcd server failed to apply command. Could you merge these changes into the 3.4 and 3.3 branches? Thanks. @jingyih @gyuho

ci failed to pass due to no space left on device.

I prefer we do not backport #11699. It was recently merged and we do not have enough soak time. Ideally we should ensure each patch release is strictly better. Backporting code refactor code adds more risk which overweights the gain in my opinion.

Agree with @jingyih. Refactored code doesn't need be backported.
