Fix kubernetes-worker charm hook failure when applying labels
**What this PR does / why we need it**:
This fixes a failure that can occur in the kubernetes-worker charm when trying to apply node labels.
The failure is rare, and can occur in two situations that I've seen:
1. kube-apiserver is not up yet
2. kubelet has not registered itself as a node yet
Rather than give up right away, let's give the services a minute to come up.
**Release note**:
```release-note
Fix kubernetes-worker charm hook failure when applying labels

New get-kube.sh option: KUBERNETES_SKIP_RELEASE_VALIDATION
**What this PR does / why we need it**:
This is an alternative solution to https://github.com/kubernetes/kubernetes/pull/49884. The goal is to be able to pull releases that were built by bazel jobs (both presubmit and postsubmit builds), which currently fail our regex validation against the version string.
This implementation is a simple "I know what I'm doing" breakglass option to turn regex validation off, whereas https://github.com/kubernetes/kubernetes/pull/49884 was to extend our validation to support the new formats of bazel build jobs. I'm testing the waters to see if this is a more palatable solution.
**Release note**:

Refactored the fluentd-es addon
Refactor fluentd-elasticsearch addon:
- Decrease the number of files by moving RBAC-related objects in the same files where they're used
- Move the fluentd configuration out of the image
- Don't use PVC to avoid leaking resources in e2e tests
- Fluentd now ingest docker and kubelet logs that are written to journald
- Disable X-Pack, because it's not free
