### Motivation
When specifying multiple roles in `.Values.auth.superUsers` the values are converted to a comma-separated list by piping the dict through `values` and `join` in helm templating, `values` however doesn't guarantee that the order of elements will be the same every time. Therefor it recommends also passing it through `sortAlpha` to sort the list alphabetically.
This is a problematic when `.Values.broker.restartPodsOnConfigMapChange` is enabled because the checksum of the configmap changes every time the list's order is changed, resulting in the statefulsets rolling out a new version of the pods.
### Modifications
Pass list through `sortAlpha`.

Fixes https://github.com/apache/pulsar-helm-chart/issues/250
### Motivation
`httpNumThreads` is hardcoded to 8 in `charts/pulsar/templates/proxy-configmap.yaml`
When trying to override in `values.yaml` by using `proxy.configData.httpNumThreads` we get an error because the keys get duplicated.
This happens because `{{ toYaml .Values.proxy.configData | indent 2 }}` doesn't deduplicate the keys and there is no other way to set `httpNumThreads`
### Modifications
Removing the key from charts/pulsar/templates/proxy-configmap.yaml and adding it to the values yaml solves the problem.

Adds dynamic superusers configuration
### Motivation
Allow dynamic superusers management. Adding new superuser entry to `.Values.auth.superUsers` will results in adding concatenated list to config
### Modifications
Change static list to dynamic one
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.
