Summary: Job creates the admin user, and outputs the recovery link.

Test Plan:
skaffold run it
```
skaffold dev -f skaffold/skaffold_cloud.yaml -p create_admin_job
```
output:

Summary:
Depends on D3793.
Adds a dev version of kibana. This will most likely get removed when Zain adds a productionized Kibana, but for now this is helpful to view log messages in Elastic.

Test Plan: Ripped my hair out using Kibana.

Summary:
This will eventually allow us to publish docs separately. We also don't usually
use customer docs when debugging so it will save us some time in building.

Test Plan: Run skaffold for docs/cloud.

Summary:
The deployment for elastic consists of two parts:
- the operator
- the elastic cluster itself
there should be one operator per k8s cluster. since we run staging and prod in the same k8s cluster, there should only be one operator for the two of them. this operator lives in the "elastic-system" namespace.
there is one elastic cluster per pixie cloud deployment. this cluster lives in plc-staging and plc for staging and prod, respectively.
the kustomize yamls are structured so that these different namespaces for the operator/elastic cluster are possible.

The operator and elastic cluster files are copied from https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-quickstart.html#k8s-deploy-elasticsearch They have been modified for linting.

For SSL:
the elastic operator creates its own SSL certs per elastic cluster by default. these certs are accesible through the k8s secrets.
We could also supply our own ssl certs, but we would need to create a new secret in the format that they're expecting:
see https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-accessing-elastic-services.html#k8s-setting-up-your-own-certificate

Test Plan: built the kustomize file and deployed it

Summary:
This fixes all the cloud dev environments. I'll test out vizier after this is checked in.

     TODO (next diffs):
      1. Try to do more dedupe with YAML files.
      2. We need to add a YAML linter (will do soon).
      3. Proxy IP/DNS discovery
      4. Create nightly deploy job.

Test Plan: Tested on all envs.
