Use a newer version of the server-provisioning-plugin.
By using a newer version of the plugin, we can reduce
the amount of build code that replicates the provisioning
logic when building overlays.
This applies to both:
* Server distribution overlay
* Adapter distribution overlay
Both overlays are created purely by using the provisioning
plugin and the feature-packs produced elsewhere in the build,
along with the admin-cli artifact when appropriate.
