Fix Swift ring management in container deployments

The ring up- and downloading was never executed if run within a
containerized environment. This is due to the fact that this manifest
gets executed within step 6(5) only. There is also an ordering issue,
which actually tries to create the tarballs before rebalancing.

This patch fixes the step conditions and also chains the tarball
creation to the rebalance.

The check to query rings on all nodes can now be disabled. This is
required on containerized environments: the local ring will be modified
and rebalanced, but rings on the existing servers are not yet modified.
Therefore a recon-check will fail, and needs to be disabled.

+    Fixes the step conditions in the Swift ring building process and
+    also chains the tarball creation to the rebalance. Adds an option to
+    disable the recon check before uploading modified rings. These fixes
+    are required to properly manage rings when used in containerized
+    environments.
