Use Same RPT token for diff requested path in mix_mode

[ldeveloperl1985]

1. User create oauth2-consumer with mix_mode

2. request to /photo path with oauth2_access_token in the header

3. introspect_access_token and cache it

4. control pass to RS plugin

5. get_rpt and check_Access = granted then cache RPT token {access_token: “AT1”, rpt: “rpt1”, permission: {path:”/post”, method:”GET”}}

6. Next time user request /picture path with the same oauth2_access_token

7. mode mix_mode then replace the header with rpt

8. check the cache. the cached path is /photo but requested path is /picture then here use the same RPT which is already in the cache i:e associated_rpt
