### Motivation
Incorrect value is being used in Pulsar Helm template `autorecovery-deployment.yaml`
### Modifications
Proper variable name set.
### Verifying this change
Fixed variable name is already set in `values.yaml` and `values-mini.yaml`.
This change is a trivial rework / code cleanup without any test coverage.
### Documentation
None needed.
Allows to opt-in for an ingress on top of the dashboard service.
This is very important in production-grade deployments where
you want to expose the Pulsar dashboard through an easy to remember URL.
### Motivation
The following errors occurs when running :
helm lint pulsar/
==> Linting pulsar/
[INFO] Chart.yaml: icon is recommended
[ERROR] templates/: render error in "pulsar/templates/zookeeper-metadata.yaml": template: pulsar/templates/zookeeper-metadata.yaml:49:20: executing "pulsar/templates/zookeeper-metadata.yaml" at <.Values.zookeeper_me...>: can't evaluate field resources in type interface {}
### Modifications
Change zookeeper_metadata in deployment/kubernetes/helm/pulsar/templates/zookeeper-metadata.yaml to zookeeperMetadata
### Result
helm lint pulsar/
==> Linting pulsar/
[INFO] Chart.yaml: icon is recommended
1 chart(s) linted, no failures
### Motivation
zookeeper failed to start because of wrong ZOOKEEPER_SERVERS was set.
### Modifications
Changed the reference of zookeeper names by how they were created.
### Result
zookeeper started successfully and broker worked as expected.
* [documentation][deploy] Update deployment instructions for deploying to Minikube
* Enable functions workers
* [documentation][deploy] Improve helm deployment script to deploy Pulsar to minikube
### Changes
- update the helm scripts: bookie/autorecovery/broker pods should wait until metadata is initialized
- disable `autoRecovery` on bookies since we start `AutoRecovery` in separate pods
- enable function worker on brokers
- provide a values file for minikube
- update documentation for using helm chart to deploy a cluster to minikube
* move the service type definition to values file
* Helm charts for deployment on GKE
* Repackaginh helm charts under deployment/kubernetes/helm
* Formatting licences
* Removing cloud specific values to enable more generic deployments
