Summary: Pull Request resolved: pytorch-labs#216 This diff is a prep diff for D76156297. Specifically, it does the following: 1. Add a `struct ReducerSpec` to replace the `64` reducer typehash. The main purpose of this struct is to add a new `builder_params` field, so we can argument the accumulator, with it, serialize it, and then send to comm actor, so comm actor can instantiate the reducer with this info. 2. Make some methods in `trait Accumulator` and `trait CommReducer` fallible. This is required by the python accumulator, because it does pickling and thus fallible. 3. Add a `typehash_f` field to `ReducerFactory`, which can be used to calculate the typehash directly. Differential Revision: D76357417
