Description

Prepared Queries were getting destroyed after 1 week, it was bloating the memory(as in the new flow, we have 100K prepared queries/day), we had to restart Lens every 12 hours.
I changed the flow:

1. Prepared Query should come from Memory for first 10 minutes. In the old flow it was in memory for 1 week.
2. After that PreparedQuery will get destroyed(old flow)
3. After 10 minutes, it should come from DB.
