[chore] set max open / idle conns + conn max lifetime for both postgres and sqlite (#1369)

* [chore] set max open / idle conns + conn max lifetime for both postgres and sqlite

* reduce cache size default to 8MiB, reduce connections to 2 * cpu

* introduce max open conns multiplier, tune sqlite and pg separately

* go fmt
