This is a pass through test failures and deprecation warnings:
* Make all ambiguous `.with(..., key: val)` use explicit hashes to
prevent test failures for argument mismatch in Ruby 3.0
* Scope down all unbounded `raise_error` to address warnings (remove
one test that was revealed to be referencing a nonexistent variable
once the raise_error was scoped.)
* Update all `any_instance` usage to new syntax to address warnings
* Allow the service cache to be cleared and do so between some tests
* Fix a small bug in with_plugin's plugin not found code path (revealed
by a scoped and_raise)
