Remove the dependency management for the modules in favour of explicit versioning

[JaidenAshmore]

Allow better sharing of version numbers in gradle.properties instead of doing constraints. The reason is that I don't want modules like API including all the constraints (e.g. avro, etc) which was not being used at all.

Release Notes

Updates how the dependencies of the library are managed resulting in the removal of the <dependencyManagement>/ constaints for each module in favour of explicitly setting the versions. The reason for this was a module like the api had a dependency management section setting values for libraries like Jackson or Avro which this module does not care about.
