NIFI-3361:

- Refactored TestGetHTTPGroovy for componentization & customization of tests.
- Ignored some TestGetHTTPGroovy tests because they cannot connect to a Jetty server running TLSv1 or TLSv1.1 (the new version of Jetty only supports TLSv1.2+). The tests are still valuable to demonstrate GetHTTP's capacity to connect to various TLS protocols, and should not be removed unless necessary.
- Refactored TestPostHTTPGroovy for componentization & customization of tests.
- Ignored some TestPostHTTPGroovy tests because they cannot connect to a Jetty server running TLSv1 or TLSv1.1 (the new version of Jetty only supports TLSv1.2+). The tests are still valuable to demonstrate PostHTTP's capacity to connect to various TLS protocols, and should not be removed unless necessary.
- Restored one of the TestGetHTTPGroovy unit tests (GetHTTP vs. TLSv1/1.1/1.2) by connecting to https://nifi.apache.org which still supports all three protocol versions (and uses JVM cacerts as truststore).
- This closes #1601
