Taken from #67350.

We currently don't track the time that a lock was acquired in the lockTable. This prevents us from accurately determining how long a lock has been held, which would be an interesting metric to export. We should augment the lockTable with this information and then expose it through a new metric.

Jira issue: CRDB-8633
