Hello,  
I am trying to use single custom container image for multiple Jenkins controllers. On my custom image I have installed common plugins for all my controllers. During helm install I hope to add plugins required for specific controller. If I use in my values file

```auto
jenkins:
  ...
  controller:
    ...
    installPlugins:
      - blueocean

```

Helm chart overwrite plugins from my custom image.  
If I will add  
`overwritePluginsFromImage: false`  
init container unable to install new plugins as /usr/share/jenkins/ref/plugins is on image read only file system.

```auto

io.jenkins.tools.pluginmanager.impl.DownloadPluginException: Unable to move blueocean-core-js to the plugin directory

```

How can I add plugins to existing custom image during helm install?
