Hello,

I've notice that Vaultwarden always keep his database pool fully connected to the database. Since my instance of Vaultwarden has a light load this resulted in 10 database connections being almost always in idle.

This PR fix this by using min_idle and idle_timeout options of the database pool manager. This allow the app to keep only 2 sessions at minimum while allowing the pool to grow when there is more load.
