Add initial GitLab CI module

[atomfrede]

A very simple initial gitlab ci configuration. Example run/project can be found here on gitlab.

The build file must not be a mustache template, but I guess it needs to be in future iterations maybe.
closes #423

Looks good to me but @pascalgrimaud is supposed to be on holiday without PC so I can merge it but can't help for the bounty here :)

Oh, the feature file is missing (to make an actual call to the module WebService). The build will fail for missing coverrage

No worries, no need to hurry.

Will have a look. Still need to learn how the ci is working.

It will probably be really close to https://github.com/jhipster/jhipster-lite/blob/main/src/test/features/github-actions.feature

Those files are run by cucumber (you can start CucumberTest as any JUnit test) and are here to make a full round call (so really calling the exposed WebServices and going through the orchestration).
