Team Device Provisioning token should allow allocation to Device Group

[hardillb]

Description

Currently a device provisioning token can target and instance or an application, but not a device group.

Being able to create a new device and directly add it to a group would make things a lot easier.

Which customers would this be available to

Everyone - CE/Starter/Team/Enterprise
