Configure installation and runtime policies for Bruschetta VMs on
Google ChromeOS. This allows for
third-party VMs to be installed by users. This feature is disabled by default.
This policy is a map of configuration IDs to VM configurations. When a VM is
installed from a configuration it is persistently associated with that
configuration ID, and any runtime policies in that configuration apply to that
VM. Multiple VMs may be installed from the same configuration on the same device.
