When running `ark <resource> create`, a request is sent to the server,
but the status is not immediately known. Inform the user that a request
was sent and provide a way to get more information on it.

When creating a restore based on a backup that doesn't exist, the
restore should be marked as invalid and the error clearly communicated
so the user understands why the restore wasn't made.

Previously, the restore was left as in progress with an error attached.

Since restores are CRDs and must be updated via a controller, there's
currently not a way to give the client immediate errors.

Support running in any namespace

Support both pre and post backup hooks

Signed-off-by: Andy Goldstein <andy.goldstein@gmail.com>

Add the ability for the Ark server to run in any namespace.

Add `ark client config get/set` for manipulating the new client
configuration file in $HOME/.config/ark/config.json. This holds client
defaults, such as the Ark server's namespace (to avoid having to specify
the --namespace flag all the time).

Add a --namespace flag to all client commands.

BackupController: do as much as possible

If a backup item action errors, log the error as soon as it occurs, so
it's clear when the error happened. Also include information about the
groupResource, namespace, and name of the item in the error.
