* Bump version to `2.9.2`
* Because the latest Pulsar image is based on Java 11, some JVM param for printing GC information has been abandoned, change to use the new JVM param. refer to https://docs.oracle.com/en/java/javase/11/tools/java.html#GUID-BE93ABDC-999C-4CB5-A88B-1994AAAC74D5 and https://issues.redhat.com/browse/CLOUD-3040.
original param | new param
--|--
`-XX:+PrintGCDetails` | `-Xlog:gc*`
`-XX:+PrintGCApplicationStoppedTime` | `-Xlog:safepoint`
`-XX:+PrintHeapAtGC` | `-Xlog:gc+heap=trace`
`-XX:+PrintGCTimeStamps` | `-Xlog:gc::utctime`
* remove JVM param `-XX:G1LogLevel=finest`
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
### Verifying this change
- [x] Make sure that the change passes the CI checks.
* Fix "unknown apiVersion: kind.sigs.k8s.io/v1alpha3"
*Motivation*
The api version `kind.sigs.k8s.io/v1alpha3` is not available anymore for kind clusters.
So all the CI actions are broken now. This PR fix the issue.
Additionally it adds a helm chart lint job to lint the chart changes.
* Trigger CI when kind cluster build script is changed
Fixes#47
### Motivation
Only create the initialize job on install.
### Modifications
- Added an initialize value that can be set to true on install, matching the documentation in the README.md
