Sets an optional retry count and a delay that the process will wait before each connection
attempt. The library will NOT retry if the device is not reachable, that is when the 30 sec.
timeout occurs. In that case the app should scan before connecting, to make sure the
target is in range.

@param count how many times should the BleManager retry to connect.
@param delay the delay between each connection attempt, in milliseconds.
             The real delay will be 200 ms longer than specified, as
             {@link BluetoothGatt#close()} is estimated to last 200 ms.
@return The request.
