Issue Summary

Currently not all the JSD REST API endpoints support Oauth2. Indeed, while for many of them you can see that the Oauth scope is documented: 

OAuth scopes required:  manage:servicedesk-customer

For others (like the below ones) this is missing and an error is returned while trying to call them using 3LO:

• Get info /rest/servicedeskapi/info
• Get articles /rest/servicedeskapi/knowledgebase/article
• Get all request types /rest/servicedeskapi/requesttype

Steps to Reproduce

1. Send a REST API request to the  /rest/servicedeskapi/requesttype endpoint using 3LO authorization

Expected Results

A list of request types is returned

Actual Results

The below error is returned:

{"errorMessages":["OAuth 2.0 is not enabled for this method."]}

Workaround

Use any other authentication method for the time being.
