provide independent archetype for carina-cucumber framework

[vdelendik]

as of now carina-demo and regular carina archetype already has example of the cucumber implementation. As result too common inside the classpath we have a conflicts because carina-cucumber is updated not so often. let's generate independent carina-cucumber archetype and sample project where we could track only cucumber based tests, dependencies etc

done: #39
also created new demo project for that: https://github.com/zebrunner/cucumber-demo

[vdelendik]

@okamara to test, please:

1. verify that archetype is released (it should appear soon on https://mvnrepository.com/artifact/com.qaprosoft/carina-cucumber-archetype)
2. register https://github.com/zebrunner/cucumber-demo repository in reporting and via launcher execute cucumber-web suite (copy template from Carin WEB updating only suite) and execute successfully on Zebrunner
3. check that new note added about generating cucumber demo on https://zebrunner.github.io/carina/getting_started/ page:

To generate Cucumber Demo project use `-DarchetypeArtifactId=carina-cucumber-archetype` in above maven command.

4. generate new Cucumber project using article in above point
5. run demo suite successfully using mvn clean test -Dsuite=cucumber-web
