Summary: Adds a non-optional EdenErrorType struct for EdenError, this can be used in case of special error case handling of errors without error message parsing. Currently this is just passed along and not consumed anywhere in the client, but later in the stack is used for specific retry of checkout if "CHECKOUT_IN_PROGRESS" on the consuming side.
