Add option to disable casting in existing Android TV / Lollipop cast settings

[GoogleCodeExporter]

It would be idea to allow a user to disable casting on a device if they so 
choose (perfectly reasonable to have the default be Allowed)

We believe there will be many instances where Android TV will be used in places 
with wifi accessed by many, but not want to allow any random person on the same 
network to start casting.

I realize app isolation can be turned on in routers and seperate wifi hotspots 
can be setup but based on so many other features being controllable via 
settings it is a shame that this is not one of them.

Apologies in advance if there is more appropriate place to post this request.

Can you explain the reason for this request?

Note that even if Cast is disabled, users on the same WiFi network can use the 
Android TV Remote Control application to control the device. I don't believe 
the software remote can be disabled for users on the network.

We believe Android TV as a platform is likely to be used in semi pubic places 
(think a dentist lobby). If the dentist is already allowing access to their 
public wifi, anyone sitting in the lobby could take control of the TV. If there 
was a way to restrict external devices from simply taking control (Via casting 
or remote control app) that could be a very useful feature. Of course by 
default this restriction would be off. A simple setting that allows or 
restricts connections from casting, the remote control app or any other similar 
features that are open by default would be welcome.
