This commit adds support for auto completion for bash and zsh
shells. A new root level command called "completion" has been
introduced, and the user can get the auto completion code by
running `ark completion bash/zsh`.
For bash completion, the built-in GenBashCompletion() from cobra
has been used, but for zsh, the built-in GenZshCompletion() is
known to cause issues. The workaround has been copied from zsh
completion code of kubectl.

This commit introduces validation logic to `ark restore logs`
command, the way it already exists in other commands like `ark
restore create`.
Before the logs for a restore are fetched from the server, the
server is contacted to check if the specified restore exists. If
it does not, it errors out.
Fixes#389

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.

This commit adds limitranges to defaultResourcePriorities as
suggested in #385.
This is done so that pods are not restored before the LimitRange
objects, because that would lead to pods not honoring the requests
and limits set in LimitRange objects.
