Support stop and set_position for virtual cover

[lodegaard]

Hey

I just found this project and it's been really helpful, but when creating som blueprints for a new cover entity I needed some more features from the virtual cover.

This PR adds support for "stop" and "set_position" for the virtual cover entity, and uses the async_call_later helper from homeassistant to fake a moving cover.

It also introduces two new config parameters for the virtual cover to control how "fast" the cover opens and closes

First, thanks for doing this.

But it doesn't work as-is on my device. It complains about async calls not happening on the event loop and doesn't stop opening or closing. I'm not sure how to update your PR so I'll just post a diff here.

These fixed it for me.

@twrecked Thanks for testing it.

I pushed a commit with your suggested changes.

The zigbee-puck I used as a reference had to be stopped explicitly once started, so I did the same for the virtual device since it was useful for debugging my blueprints.

Many thanks for this!

Thank you very much for this!

When I try to set a position (by calling a service or using the slider), the virtual cover opens/closes all the way (or until I pause it). Any advice on this?
