Filter test methods for execution by regex from configuration file

[oomelianchuk]

In some projects, it's required to execute only the test, the class name, method name, and test id of which match the specific regex. Although maven-surefire offers the way to do it via -Dtest=%=regex[.*.*] option, this only works for execution in the console.

It would be great to have a feature, that would allow such filtering for execution in IDE and also controlling the regex via a configuration file.

Implementation suggestion:

• read regex from neodymium.configuration file
• in NeodymiumRunner.computeTestMethods filter the computedTestMethods list by the regex

@oomelianchuk Please add/adjust the documentation regarding this feature and comment here when done. So we can perform the final test.
