Returns the {@link DNEnvironment} object relating to the pipeline config for this environment. The environment YAML file (e.g. project1-uat.yml; see docs/en/pipelines.md) contains two variable called `DependsOnProject` and `DependsOnEnvironment` - these are used together to find the {@link DNEnvironment} that this environment should rely on.
