Extend CesiumCameraManager to control which Unreal cameras are used by tilesets #1768
Description
With the help of a member of the community, we added a CesiumCameraManager to Cesium for Unity awhile back. It gives uses control over which cameras are auto-discovered, and also allows them to manually tell the system to use particular cameras that it wouldn't otherwise discover itself.
This comment describes how it works:

We should add something similar to Cesium for Unreal. We already have a CesiumCameraManager in Unreal, but a) it doesn't allow any of the cameras that are auto-discovered to be excluded, and b) it only allows additional cameras to be very manually specified.
