Yealink Hot Desking Support

Hello,

I worked on a small PR to support hot desking with Yealink on wazo-phoned service. The PR is here https://github.com/wazo-platform/wazo-phoned/pull/34

If someone want to make some tests and give me some feedbacks it would be nice. Looks like it’s a an important feature for phone desk.

Your input is welcome to help us to prioritize this dev.
