URL: https://github.com/apache/pulsar/issues/7354


   **Is your feature request related to a problem? Please describe.**
   
   When registering or updating a function via the REST API using a jar url that has the `user:pass` basic auth scheme is unsupported.
   
   Currently when a jar url with basic-auth credentials is used an error like the following is returned and the register/update call to the REST API returns a `400 - Bad Request`
   
   `Bad Request - {"reason":"Encountered error \"Server returned HTTP response code: 401 for URL: <JAR_URL_HERE>" when getting Function package from <JAR_URL_HERE>"}`
   
   **Describe the solution you'd like**
   The basic-auth credentials in the jar url should be forwarded along to the destination url and used to download the function jar
   
   **Describe alternatives you've considered**
   The only alternative is to manually hit the jar url and download the jar to the server where the application that's hitting the API is running and using the `file://` url type. Though, this approach won't work in many cases and is why the remote jar url option is provided.
   
   **Additional context**
   Hitting the same jar url with basic-auth credentials in a browser prompts a download of the jar, so the url is valid.
