Rebase after https://github.com/cryostatio/cryostat3/pull/449 is merged and that test failure will be fixed.

Thnx @andrewazores This is very helpful. I wasn't sure what was causing the test failures!

Looking good! I'd like to see a little refactoring to get rid of the static methods next. You can add a method to Producers.java to return a singleton instance of the URIUtil and inject that wherever it's needed, and I think you could even clean it up so that this is the only place where the new uri-range String property is injected, so that the Custom Discovery (or any other caller) only needs to supply the URL/URI to be tested and the range is already inferred from configuration.
