* Add missing license headers and .rat-excludes
* Fix .rat-excludes files
### Motivation
As part of our updated release process, we need to make sure that all relevant files have license headers.
### Modifications
* Add license headers formatted appropriately for each file type
### Verifying this change
The follow script shows that the solution is complete:
```shell
$ java -jar ../apache-rat-0.15/apache-rat-0.15.jar . -E .rat-excludes
Ignored 18 lines in your exclusion files as comments or empty lines.

### Motivation
There was a suggestion [in a dev mailing list discussion](https://lists.apache.org/thread/bgkvcyt1qq6h67p2k8xwp89xlncbqn3d) that the Helm chart's appVersion should be used as the default image tag.
### Additional context
There are some limitations in Helm. It is not possible to set "appVersion" from the command line. There's in an open feature request https://github.com/helm/helm/issues/8194 to add such a feature to Helm.
### Modifications
- change default values.yaml and set the tags for the images that use the Pulsar image to an empty value
- add "defaultPulsarImageTag" to values.yaml
- add a helper template "pulsar.imageFullName" that contains the logic to fall back to .Values.defaultPulsarImageTag and if it's not set, falling back to .Chart.AppVersion
- use the helper template in all other templates that require the logic
Fixes#125
### Motivation
The default images in the values.yaml are in docker hub. This PR allows us to provide image pull secrets for the containers which will allow us to get around Docker Hub's rate limiting if the nodes are not logged into Docker Hub.
### Modifications
Added a new template to generate `imagePullSecrets`, and included them in the deployments and statefulsets. This will only add them if they are specified under `images.imagePullSecrets`
### Verifying this change
- [] Make sure that the change passes the CI checks.
It remains possible to override the current release namespace by setting
the `namespace` value though this may lead to having the helm metadata
and the pulsar components in different namespaces
Fixes#66
### Motivation
Trying to deploy the chart in a namespace using the usual helm pattern fails for example
```
kubectl create ns pulsartest
helm upgrade --install pulsar -n pulsartest apache/pulsar
Error: namespaces "pulsar" not found
```
fixing that while keeping the helm metadata and the deployed objects in the same namespace requires declaring the namespace twice
```
kubectl create ns pulsartest
helm upgrade --install pulsar -n pulsartest apache/pulsar --set namespace=pulsartest
Error: namespaces "pulsar" not found
```
This is needlessly confusing for newcomers who follow the helm documentation and is contrary to helm best practices.
### Modifications
I changed the chart to use the context namespace `.Release.Namespace` by default while preserving the ability to override that by explicitly providing a namespace on the commande line, with the this modification both examples behave as expected

### Motivation
Give the ability to deploy multi-cluster instance on K8s clusters with non-default `clusterDomain`, and connect to external configuration-store
### Modifications
- give the ability to change cluster's name
- give the ability to change `clusterDomain`
- fix external configuration store functionality
- use broker ports variables
- use label templates, and add `component` label in several places
### Verifying this change
- [x] Make sure that the change passes the CI checks.
