Add support for CarInfo

[superm1]

Is your feature request related to a problem? Please describe.

Add support to the mobile application for Android to request CarInfo information when connected to Android Auto.

Of particular interest to me is what the current connected car is and what the EV battery level is, but I can see tons of opportunity with other things that can be reported as well.

Describe the solution you'd like

Add sensors to indicate Car Information.

Describe alternatives you've considered, if any

Using EVNotify and OBD2 dongle to get EV level. This is functional but a bit clunky and insecure. Since Android auto offers such an API, it makes sense to me that the HA AA application should use it!

Additional context

This was found as part of reading through the announcement for HA android auto support and looking at the API documentation for AA.

+1 this would be next level. I am also trying to pull info from the car using an OBD dongle but it is flaky at best. Access to EV battery level is also what I am after as well as total km (odometer)
