Upgrading to k0rdent 1.0.0

The actual process of upgrading k0rdent to 1.0.0 doesn't require any additional steps beyond those listed in the general upgrade instructions, but there are several changes that may affect ancilliary artifacts.

Specifically, as part of ongoing improvements to the k0rdent API, we have upgraded the apiVersion from v1alpha1 to v1beta1. This change introduces enhancements in stability and forward compatibility, but may require updates to any existing automation, scripts, or integrations built against the earlier version.
