This commit changes the groupId to the above mentioned one
so that S3 uploads will end up in the right bucket. This will
allow the Elasticsearch plugin manager to install the commercial
plugins like
```
bin/plugin install {watcher,shield,license,marvel}
```
like the official ones.

This removes the parent from x-dev-tools because we won't be publishing this artifact to sonatype's repository.
