The main Ark code was hard-coding specific support for AWS, GCE, and
Azure volume snapshots and restores, and anything else was considered
unsupported.
Add GetVolumeID and SetVolumeID to the BlockStore interface, to allow
block store plugins to handle volume snapshots and restores.

If backing up specific namespaces with "auto" cluster resources, the
actual namespace objects themselves were not being included in the
backup. Restore would create them but any labels or metadata would be
lost.
Instead handle the special case of namespace as a cluster level resource
we may still need, even if excluding most cluster level resources.

Previously the directory structure separated resources depending on
whether or not they were cluster or namespace scoped. All cluster
resources were restored first, then all namespace resources. Priority
did not apply across both and you could not order any namespace
resources before any cluster resources.
This restructure sorts firstly on resource type.
resources/serviceaccounts/namespaces/ns1.json
resources/nodes/cluster/node1.json
This will break old backups as the format is no longer consistent as
announced on the Google group.
