* Limit database connections (#564)

- Add new options to the config file database:
      max_open_conns: 100
      max_idle_conns: 2
      conn_max_lifetime: -1
- Implement connection parameter setup on the *DB (database/sql) in internal/sqlutil/trace.go:Open()
- Propagate the values in the form of DbProperties interface via all the
  Open() and NewDatabase() functions
