Prepare codebase for dynamic DMaaP configuration
From now on, there is only one single place
where we can create whole app core concerning sending events
and it has a single entry point, based on DMaaP configuration.
It can be used to rebuild part of app that is responsible
for sending events dynamically.
Changes are in scope for the dynamic DMaaP config feature.
+ bumped up code coverage a bit
