Shuffle play in Android Auto

[tmaoz]

Is your feature request related to a problem? Please describe.
When playing a local playlist through the Android Auto interface, there is no option to play the playlist in shuffle mode while the app on the phone has this feature.

Describe the solution you'd like
In Android Auto, when viewing the song list of a selected playlist, an extra button (maybe next to the search icon on the top right or in the bottom right corner) to start playback in shuffle mode would be amazing!

A screen capture from Android Auto is attached to show the screen in question. (I'm running a desktop head unit to be able to connect my phone and grab the screen cap).

Describe alternatives you've considered
In the Playlist listing view, currently there's a "right" button showing and when you select the playlist is opens the song list. As an alternative to the above, a shuffle button on the playlist entry in the playlist listing would also be great - this can simply shuffle the list of songs before populating the song list and then starting playback from the first song would actually play in shuffle mode.
A screen cap of the playlist listing view is also attached.
