[AA] Enable test-specific configuration of write access permissions

- In general, Analysis API tests forbid write access because the
  Analysis API should not be used from write actions. However, in some
  cases we might want tests to e.g. modify PSI, which requires write
  access. This change allows `AnalysisApiTestConfigurator`s to enable
  write access for the specific test.
