snap connect myapp:camera out-of-the-box

[Dev Dev]

Hi,

Anyone can give me more information (ETA, how it will works) about the
connection to camera. Right now, I need to ask my users who installed
myapp via the Software Center to open a terminal and run:
sudo snap connect myapp:camera

It needs to be automagically connected.

I reported this issue here:

Thanks
