Description
When configuring a NiFi-registry client within NiFi the user can enter whatever URI they desire. However if the user enters a URI that does not contain http/https the URI is not validated. I typed "htp://" for example instead of "http://". I restarted nifi and nifi would not restart giving an error in the logs that is included below. This prevented NiFi from starting without first manually fixing the controller service entry for the nifi-registry. This seems to only happen when you "update" the URI for the NiFi-Registry. It seems that client side validation is not occuring when updating the URI. This allows for the system to get in an invalid state if someone updates the URI incorrectly.
