Description:
Allow policy that would limit Bluetooth device pairings to individual users instead of devices. Alternatively drop Bluetooth pairings when a new user logs in.

Use case:
A primary enterprise use case for ChromeOS devices is as loaners and shared devices. Ideally devices should be shared with as little human intervention as possible meaning that policies should be able to control the level of customization that an individual user can do to a device. With Bluetooth one user can pair mice, headsets, etc and they remains paired to that device even if that device has been passed to another user. This creates the undesired effect of those BT devices reconnecting to the shared device unexpectedly.

Motivation:
Our team manages the Google Open Source project "Grab n Go Loaners" (github.com/google/loaner) which is a low-touch ChromeOS loaner solution. We've had user reports that this is a problem. I can imagine as the shared use case grows internally and externally this might become a bigger problem.

Existing workarounds:
You can disable Bluetooth on shared devices but that makes it difficult for users that have specific needs (perhaps they rely on Bluetooth accessibility devices for example).
