Problem connecting to BLE devices with Windows

See original GitHub issue

bleak version: 0.4.2
Python version: 3.7.3
Operating System: Windows 10

Description

On linux (backends/bluezdbus/client.py), connect() function uses discover() with a timeout : await discover(timeout=0.1, loop=self.loop) (here).

On windows (backends/dotnet/client.py), connect() function uses discover() with a defined value: devices = await discover(2.0, loop=self.loop) (here), which leads to random errors due to the fact that Windows is unable to discover the device to connect to within 2 seconds.

Since discover() has a timeout var, it can be good to use timeout=2.0 instead of 2.0 in client.py, so developers can adapt the value without having to manually change Bleak.
