Allow configuration of Authorization tokenURL

[dkirrane]

Content & configuration

Using openapi: 3.0.2 yaml I want to make the tokenURL configurable. Even just let the user edit it.

Swagger/OpenAPI definition:

openapi: 3.0.2
info:
 title: Demo
 version: '1.0'
servers:
 - url: '/api'
   description: Internal API (relative path)
security:
 - OAuth2: []
paths:
 /hello:
   get:
     summary: Your GET endpoint
     operationId: getHello
     responses:
       '200':
         description: OK
       '400':
         description: Bad Request
       '401':
         description: Unauthorized
components:
 securitySchemes:
   OAuth2:
     type: oauth2
     description: This API uses OAuth 2
     flows:
       clientCredentials:
         tokenUrl: "{protocol}://{server}:{port}/auth/realms/system/{tenant}/openid-connect/token"
         scopes: {}

Currently the user cannot change the tokenUrl:
