Xbox integration: Add common delimiter/namespace to entities

I really enjoy the Xbox Integration and use it on my dashboard to quickly show what friends are up to.

However, given that these are configured as various sensors, and they change frequently, many logs are generated in the Recorder. Further, since the Recorder cannot filter by Integration, and the sensor entity IDs don’t have any common delimiters, this means many custom entries in the recorder: config.

Adding a pseudo-“namespace” to these entity ids: e.g. binary_sensor.xbox_friend1, sensor.xbox_friend2_status would be a great way to utilize this Integration while allowing folks to easily target them in other areas of the HA system.
