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)

Handle the case where a BackupItemAction may return nil for updatedItem,
meaning "no modifications to the item". The backupPVAction does this,
and we were panicking instead of accepting it.

If you want to test changes to the ark server without having to rebuild
and redeploy the ark container, this change allows you to do something
like this (assuming you've created your cloud credentials file):
AWS_SHARED_CREDENTIALS_FILE=credentials-minio ark server -n heptio-ark

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.
