juju: Revert "Bugfix for erroneous upgrade needed messaging ..."

**What this PR does / why we need it**:

This reverts https://github.com/kubernetes/kubernetes/pull/60873, which made it where the kubernetes-worker charm always requires a resource to be attached. This newly introduced requirement is a blocker for some of our users, so we have to revert this.

This PR fixes https://github.com/juju-solutions/bundle-canonical-kubernetes/issues/545 but reintroduces https://github.com/juju-solutions/bundle-canonical-kubernetes/issues/504. We can't really fix this in the charm, we'll have to get it fixed in juju instead.

**Release note**:

```release-note
