SoapUI based ETS: function int ETF-SEL required for URL encoding of parameterized requests

[jonherrmann]

HTTP requests steps that possess parameterized key value pairs are not natively encoded by SoapUI.

• check if we can register some kind of HTTP request post processing or otherwise
• implement a function that needs to be called explicitly before these request are send

Use TestRunListener.beforeStep()

Closed though fix in ii-commons-util and etf-owsgtl. See also Geonovum/etf-test-projects-inspire#67 (not yet integrated, as new SoapUI version 5.2.1 is required)
