Review Comment:
I'm not necessarily looking for a change, but wanted to understand the
rationale.

> KnoxToken extension for OAuth Token Flows
> -----------------------------------------
>
> Key: KNOX-3028
> URL: https://issues.apache.org/jira/browse/KNOX-3028
> Project: Apache Knox
> Issue Type: Bug
> Components: JWT
> Reporter: Larry McCay
> Assignee: Larry McCay
> Priority: Major
> Fix For: 2.1.0
>
> Time Spent: 2h 40m
> Remaining Estimate: 0h
>
> This change will extend the existing TokenResource for KNOXTOKEN service to
> include OAuth specifics such as expected URL, error messages and flows to
> support Token Exchange Flow and Token Refresh.
> This is being driven by a specific need to proxy access to the Iceberg REST
> Catalog API. In this specific usecase, we need to intercept the use of the
> following endpoint URLs and serve the token exchange flow for the
> authenticating user.
> {code}
> /v1/oauth/tokens
> {code}
> Details for these requirements can be found in the openapi description for
> the catalog API [1].
> In addition to this usecase, we should add generic support for the token
> exchange flow with more generic URL that better aligns with what others use.
> {code}
> /oauth/v1/token
> {code}
> We will support the use of the "oauth" service name within the existing
> KNOXTOKEN service with an extension of the TokenResource which adapts the
> existing KNOXTOKEN behavior to the expectations of clients on OAuth responses.
> In order to support both URLs, the deployment contributor will need to
> register a url pattern for each usecase and the resource path within the
> jersey service will need to accommodate the dynamic nature of the Iceberg
> REST Catalog API which will add the catalog API service name as well.
> {code}
> /icecli/v1/oauth/tokens/
> {code}
> Where "icecli" may be some configurable service name and need to match to the
> incoming URL.
> We will wildcard that by making it a regex matched path param.
> We will also need to accommodate a first-class Knox pattern and service name
> of "oauth" and only allow "token" or "oauth" after the v1 with the remaining
> path fragment being optional for the iceberg specific "tokens".
> Not pretty but it will work.
