Right now TestStorage is used to contain all the important data like clusterName etc. and we use it as testStorage.getClusterName() to stay consistent. This is however not the only usage as in some tests there are variables defined with the test storage getter, that might be at first sight a good approach but there are cases where this might get a bit confusing. So there is a need to clear up where do we use the redefined variables instead of direct getter approach.

In this sssue we should focus on adding necessary fields, other refactors should be done elsewhere
