Refactor plugin management:
- support multiple plugins per executable
- support restarting a plugin process in the event it terminates
- simplify plugin lifecycle management by using separate managers for
each scope (server vs backup vs restore)

When the BackupDeletionController processes a request, set the request's
backup-name and backup-uid labels if they aren't currently set.

Make sure a DeleteBackupRequest has its Spec.BackupName filled in. If
not, record an error in the status and mark the request as processed.

Always request DeleteBackupRequests for a given backup so we can show
failed deletion attempts if you try to delete a backup that has PV
snapshots when Ark doesn't have a persistentVolumeProvider configured.
When creating a DeleteBackupRequest, include a label for the UID so we
can match based on name and UID when associated DeleteBackupRequests
with a given backup.

We ran into a lot of problems using a finalizer on the backup to allow
the Ark server to clean up all associated backup data when deleting a
backup.
Users also found it less than desirable that deleting the heptio-ark
namespace resulted in all the backup data being deleted.
This removes the finalizer and replaces it with an explicit
DeleteBackupRequest that is created as a means of requesting the
deletion of a backup and all its associated data. This is what `ark
backup delete` does.
If you use kubectl to delete a backup or to delete the heptio-ark
namespace, this no longer deletes associated backups. Additionally, as
long as the heptio-ark namespace still exists, the Ark server's
BackupSyncController will continually sync backups into the heptio-ark
namespace from object storage.
