StackTransformer is a standard mechanism for transforming the default shape of the Stack. It is a Stack.Transformer with a name. Registration and retrieval of transformers from global state is managed by StackServer.DefaultTransformer. The transformers will run at materialization time for Finagle servers, allowing users to mutate a Stack in a consistent way.
Warning: While it's possible to modify params with this API, it's strongly discouraged. Modifying params via transformers creates subtle dependencies between modules and makes it difficult to reason about the value of params, as it may change depending on the module's placement in the stack.
