Other parts of the system make use of a "type" field, while the
AuthenticateResponse sets a "token_type" on the response attributes
directly. Rename this field to "type", and move it up to the response
level, to be more consistent with other RPCs.
Also adds a new field to the AuthenticateRequest, "type" which will
replace the "token_type" field over time.
This moves the generated pb files to the `sdk` module. This allows third parties to make use of them if desired (e.g. in upcoming plugins) and moves away from the `gen` nomenclature in the directory, since we are going to be adding some extra interface functions to the messages.
* add new error funcs which take a ctx and deprecate existing funcs
* use context where available when writing error events
* remove circular internal/errors pkg dep
* suppress some chatty errors using errors.WithoutEvent()
* convert auth oidc funcs to take context where needed to write events
