pulsar-proxy: tls Certname

[cccdemon]

Is your feature request related to a problem? Please describe.
When you want to use a valid / signed certificate for pulsar-proxy, the helm charts do not use the certname you entered in the values file:
Example:
proxy:
enabled: true
cert_name: my-valid-certificate # use this certname
createCert: false # set to false if you want to use an existing certificate

Results in certificate name within the Proxy as "pulsar-my-valid-certificate"

Describe the solution you'd like
just use the cert_name i`ve entered

Describe alternatives you've considered
remove the option of "using the releasename as prefix"

Additional context
File: proxy-statefulset.yaml

{{- if .Values.tls.proxy.createCert }}
secretName: "{{ .Release.Name }}-{{ .Values.tls.proxy.cert_name }}"
{{- else }}
secretName: "{{ .Values.tls.proxy.cert_name }}"
{{- end }}

@cccdemon Sounds like a useful improvement. Would you like to contribute a pull request? This Helm chart is community maintained so pull requests are preferred so that we can improve the chart together over time.

@lhotari never did that, but I will give it a try :-)
