* 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.

```
Updates CA name generation to be configurable allowing the swapping in of a CA.
### Motivation
We recently swapped out cert issuers and found that with the current helm chart we were unable to do a hot swap without downtime (via helm) because the CA cert name is not configurable. Being able to change the name of the CA allows us to create a new CA first -> Validate -> then swap over in follow up apply/release.
### Modifications
Adds the ability to specify the suffix used to generate the CA name (not the whole name in order to preserve back compatibility regardless of the release name.)
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.
