refactor(types): migrate errors to types module

[ryanchristo]

Description

We created an errors module with a single file listing grpc errors. I think reusable errors was the right idea but this should be included in the types module. We may want to have a separate module in the future but given the size of this module and the extra steps it adds to the release process, I think it would be better to have the errors added to the existing types module.
