Also add `<version>1.7.0-SNAPSHOT</version>`? Seems redundant, but from what I recall the problem during preparing for the release was the following:
* to prepare for a release, the snapshot dependency on the jclouds "main" projects needs to be turned into a stable dep
* to be consistent, that should probably affect the `jclouds.version` **and** the dependency on `jclouds-project` equally
* but if the labs version simply inherits from `jclouds-project`, it's no longer a snapshot after the changes and can't be released.
