Remove explict getters and setters from common pipeline environment

[marcusholl]

We get getters and setters generated automatically.

IMO we should be able to explain each line of code. For me it is hard do explain why we have getters and setters, since groovy is able to automagically create getters and setters. Does anybody know a good reason for writing down the getters and setters explictly?
