The problem/use-case that the feature addresses
Mostly to allow external tools to perform a consistency check between servers (e.g. master and replica) The issue is that when sampling server A some key may exist but when checking server B it might already be logically expired, thus causing the consistency check to fail
Description of the feature
A debug subcommand/config that tells Redis to ignore all TTLs (i.e. completely turn off lazy/active expiry)
