Jira Link: DB-3155
We should delay deadlock detection for some configurable amount of time, say 1s, similar to Postgres. This will allow us to avoid the overhead of deadlock detection in cases where blocked transactions are unblocked quickly.

See deadlock_timeout in https://www.postgresql.org/docs/current/runtime-config-locks.html

This can help with the perf of deadlock detection.
