KIP-263 — Allow broker to skip sanity check of inactive segments on broker startup

Discarded Broker

KIP-263 (discarded) proposed a `sanity.check.all.logs.enabled` broker config to skip index-file sanity checks for inactive log segments at startup and defer them to background threads or request-handler threads on first access. The full check requires opening every segment's index into the page cache and scales linearly with segment count, causing broker restart times to grow to hours in large clusters and blocking rolling restarts.
