Cucumber JSON reader: improve outlines support

[delatrie]

Scenario outlines are reported differently across various cucumber JSON dialects. Some interpolate the example table name and the row number into the scenario's ID (Cucumber-Ruby, Cucumber-JS). Others - into the scenario's name (Behave).

We should carefully review different dialects and implement an algorithm to extract such IDs and convert them into the test's parameters or embed them into fullName to keep each test separated.
