Add support of methods with varargs and #{options.option ...}

[snuyanzin]

There 2 issues:

1. Current code can not resolve the code with varargs e.g. Options.option
2. Options does not have option method with String varargs which is implied by FakeValuesService

This PR adds check if there is varargs in method args and supports it, also adds Options.option with String varargs to make it working like

#{options.option '12','345','89','54321'}

the PR is same as DiUS/java-faker#703

Hi @snuyanzin , thanks again. It took me a bit longer to review this one, since I've added similar code recently, though I added it to Faker itself. I'll move my code also to Options.
