Constructor injection

[John-Wiens]

PR Details

Description

This PR cleans up the intersection API by switching spring to use constructor injection. This will help to prevent null pointer errors when dependencies are not available in the future.

How Has This Been Tested?

Unit tests were run to make sure all components are still functioning. A selection of REST endpoints were verified manually by running the CV-Manager GUI.
