Instead of requiring the Ark admin to specify a "location" in the azure
persistentVolumeProvider config (meaning only a single location is
supported), get info about the disk (for its location) when creating a
snapshot, and get info about the snapshot (for its location) when
creating a disk from a snapshot.

Move ark server deployment & minio deployment to a separate namespace
from the backups/schedules/restores/config because backups now have a
finalizer. If everything lives in one namespace, you have to delete all
the backups and wait for the GC controller to process them and remove the
finalizer from each before deleting the namespace.
By moving the server into a separate namespace, users can now delete the
heptio-ark namespace the normal way (kubectl delete), and once that
namespace is fully removed, they can delete the heptio-ark-server
namespace.
