Scenario Simulation feature

We want to create a new feature in Drools WB and core to support scenario testing.
The scenarios will be executed in a simulation mode to let the user able to test his system and export results for post-simulation analysis/no regression.

Drools WB should support user in scenario definition (i.e. define facts template) and then let insert input data (single or bulk) with corresponding expected results.
Drools core should support steps definition with a fluent API and then simulation runs. We should also support a JUnit-like output format.

This feature will also dismiss current Test Scenario asset
