We are refactoring the supervisor test suite into unit tests (for algorithms an domain model tests) and integration tests (for interaction with out-of-process dependencies). This means the current test suite needs to be classified into these two categories, and fixed whenever possible. This commit moves the test suite under the `test/legacy` folder, this folder should be progressively migrated and eventually removed. Subsequent commits will begin to split these files into unit and integration whenever possible. Depends-on: #1996 Change-type: patch
