Unversionned package-lock.json file

[severo]

When compiling geonetwork inside of https://github.com/georchestra/georchestra, following: https://github.com/georchestra/georchestra/blob/18.06/docs/build.md#build-the-modules, and then launch

git status

we get

HEAD detached at efaded366
Untracked files:
  (use "git add <file>..." to include in what will be committed)

        package-lock.json

nothing added to commit but untracked files present (use "git add" to track)

We should do one of the following:

• add this file to .gitignore
• version this file

I understand that the good practice is to version it, as stated in the official npm documentation: https://docs.npmjs.com/files/package-lock.json

Note that I don't fully understand how we manage the various georchestra submodules and their branches, so I don't want to propose a PR for the moment.

+1 on versioning it, as we already do for https://github.com/georchestra/georchestra/tree/18.06/console/src/main/webapp/manager

I don't fully understand how we manage the various georchestra submodules and their branches, so I don't want to propose a PR for the moment.

georchestra master uses geonetwork-3.4-master
georchestra 18.06 uses geonetwork-3.4-18.06

We also "cascade merge" fixes from geonetwork-3.4-18.06 into geonetwork-3.4-master & update submodules accordingly ... I know this is complex but we did not find a better way !
