Align Cucumber test methods to Java naming conventions

[e-pettersson-ericsson]

Description

Right now the functionaltests directory is being ignored by Codacy. Removing this ignore will cause many errors that needs to be adressed. For example method names. Change the method names in our cucumber tests to align with Java standard naming conventions of using camelCase.

Motivation

Aligned with the rest of the source code. + we can include code style check of functional tests in Codacy.
