Add support to log in using site name

[tjamet]

In the tydom app, users tend to refet to their homes with a friendly name.

Currently, we require the full mac address which is not trivial to get.

With this change, we will be able to provide the site name and perform a login using the site name. This contributes to improving the user experience configuring the integraiton for the first time
