Requests the new connection priority. Acceptable values are:
<ol>
<li>{@link BluetoothGatt#CONNECTION_PRIORITY_HIGH}
- Interval: 11.25 -15 ms, latency: 0, supervision timeout: 20 sec,</li>
<li>{@link BluetoothGatt#CONNECTION_PRIORITY_BALANCED}
- Interval: 30 - 50 ms, latency: 0, supervision timeout: 20 sec,</li>
<li>{@link BluetoothGatt#CONNECTION_PRIORITY_LOW_POWER}
- Interval: 100 - 125 ms, latency: 2, supervision timeout: 20 sec.</li>
</ol>
Works only on Android Lollipop or newer. On older system versions will cause
{@link Request#fail(FailCallback)} callback or throw
{@link no.nordicsemi.android.ble.exception.RequestFailedException} with
{@link FailCallback#REASON_REQUEST_FAILED} status if called synchronously.
Starting from Android Oreo you may get a callback with the interval, latency and timeout
using {@link ConnectionPriorityRequest#with(ConnectionPriorityCallback)}.
<p>
The returned request must be either enqueued using {@link Request#enqueue()} for
asynchronous use, or awaited using await() in synchronous execution.

@param priority one of: {@link BluetoothGatt#CONNECTION_PRIORITY_HIGH},
                {@link BluetoothGatt#CONNECTION_PRIORITY_BALANCED},
                {@link BluetoothGatt#CONNECTION_PRIORITY_LOW_POWER}.
@return The request.
