Using strings as events is deprecated and will be removed in a future version

[enterprisebug]

I am using the following command to generate my new Grafana project:

npx @grafana/toolkit plugin:create my-plugin

After deploying and browsing to the dashboard i see in the console:

Using strings as events is deprecated and will be removed in a future version. (init-edit-mode)
Using strings as events is deprecated and will be removed in a future version. (render)
Using strings as events is deprecated and will be removed in a future version. (data-error)

The code in the template looks like this:

this.events.on('init-edit-mode', this.onInitEditMode.bind(this));
this.events.on('render', this.onRender.bind(this));
this.events.on('data-error', this.onDataError.bind(this));

Hint
fix should be easy: use constants from `PanelEvents`` namespace
