[DMN Designer] Changing the default DMN Namespace

Currently, the default DMN Namespace looks like the following:
https://github.com/kiegroup/drools/kie-dmn/

{#########}

It would be more convenient to have something related to the actual project where the DMN project is created, like:
http://{MavenGroupId}/definitions/{#########}

[Update]
Team agreed the most important part is to replace the github part from the current default namespace. The form of the new default namespace will be based on resources available for this jira.
