Managed resource inventory

v0.12.0-beta

Managed resource inventory. The agent can now enumerate on demand everything it hosts for projects (containers, deployment folders present on disk, per-project networks), with each container's organisation/project/application attachment. This lets the hub compare the server's real state to what it holds in its database, and therefore detect then purge orphan resources (containers or services left behind by a deleted or abandoned project). A read-only operation, with no effect on containers.
