aioble: Pass additional connection arguments to gap_connect.

This allows the following arguments to be passed to `device.connect()`:

* scan_duration_ms
* min_conn_interval_us
* max_conn_interval_us

These are passed as-is to `gap_connect()`. The default value for all of
these is `None`, which causes gap_connect to use its own defaults.
