Helm upgrade fails with immutable modification error

[tscurtu]

This manifests on the 1.1.17 Helm charts. It happens both for when there previously was a chart installed from sources and from an official release. Uninstalling works around the error.

This was caused by the fact that the environment had previously had a version of deployment with a non-dedicated Socketio installation.

When upgrading from a previous non-dedicated version of the deployment to >= 0.35.0, you now have to uninstall the deployment first.
