Major Description
Currently when defining a new NiFi service, if the url is https, then the user is required to supply the configuration for the keystore/truststore to use for creating an SSLContext to talk back to NiFi.
In cases where the ranger's truststore already trusts the certificates used by NiFi, there should be a way to just use ranger's SSLContext and not have to provide any information.
This is similar to the solution for RANGER-2567 for communicating with an SSL enabled Solr.
