Use MAX_LOCK_TTL in RedisLockManager to avoid premature lock expiration

App servers should not lower the redis structure TTL of locks set
from CLI scripts, which is what would typically happen before if
they touched the same keys. Instead, keep a high lock record TTL
and rely on the logical TTLs for expiry semantics.
