fix: group configurations are not upgraded correctly

[0utplay]

Motivation

When upgrading a v3 group to v4 the environmentVariables map must be added to the configuration. Due to the fact that Document#contains does not check for a null value the map is not properly set and therefore results in an error when starting a service.

Modification

Added a new method containsNonNull to the document that checks that the document contains a value mapping that is non-null.

Result

Groups and tasks are converted correctly
