NIFI-13720: Component is not reloaded when the isolation key depends on service property

[mark-bathori]

Summary

To be able to create a system test for the PR the system-test-extension had to be restructured because when a component is annotated with @RequiresInstanceClassLoading and contains a controller service property then the framework does not allow the component to be in the same bundle as the service API.

I suggest not renaming the variable/method from additionalResourcesFingerprint to componentFingerprint but leaving it as it is now.
To be fully consistent, the interface methods (isReloadAdditionalResourcesNecessary(), reloadAdditionalResourcesIfNecessary()) should be renamed too. However, I don't think it is worth changing these API methods.
Also, the isolation key was added in the "additional resources fingerprint" earlier so it was already a bit inconsistent name. It will be no better or worse due to the change in this PR.

@markap14 Do you have any other idea to overcome the issue mentioned in the PR summary? (other than restructuring the system tests module)
