Helm chart is too big to be installed through rancher manager

**Describe the bug**
Since version 4.0.0 pulsar helm chart is too big (> 1 MB), and it makes it impossible to install through Rancher Manager

**To Reproduce**
If you try to install pulsar 4.1.0 through rancher manager interface, you will have an error raised:

message=Secret "helm-operation-2cbbx" is invalid: data: Too long: must have at most 1048576 bytes

**Additional context**
Rancher is storing the helm chart tar ball in a secret, nevertheless, since victoria metrics dependency was added, the size of the helm tar ball has increased to be bigger now than 1 MB. And in kubernetes, by default, secret cannot be bigger than 1 MB, so it is cannot be installed.

No specific files or tests are named. Start by inspecting the Helm chart package and its Victoria Metrics dependency, then reproduce a Pulsar 4.1.0 installation through Rancher Manager; done means the packaged chart is no larger than Kubernetes' 1 MB Secret limit and installs successfully.
