Preserve custom init_containers

[g-braeunlich]

Would it be possible to not override self.init_containers but only add the project-manager init container in persistent_bhub_config.py?
E.g.

if not any(ic["name"] == "project-manager" for ic in self.init_containers):
    self.init_containers.append({
            "name": "project-manager",
            "image": self.image,
            "command": command,
            # volumes is already defined for notebook container (self.volumes)
            "volume_mounts": [projects_volume_mount],
        })

That sounds okay to me, but it would be nice to know/document an example how else is initContainer is being used :)

In my case: I want to automatically do

git config --global user.name ...
git config --global user.email ...

Therefore I would like to subclass PersistentBinderSpawner and add another init container doing that.
I cannot wrap start() and add it afterwards, because at the end of start() the spawning will start.

@g-braeunlich jupyterhub/binderhub#1081 looks related?

Yes but in my case, I dont want to modify the image. I want to modify the users persisted volume
