81a4dbcf8f Bluetooth: Allow to set required security for connection
This adds bt_conn_security function that can be used to elevate
security on connection. If device is not paired it will trigger
pairing first.

For now only JustWorks pairing is supported so full security level
tracking is not needed as only medium level is supported.
