Plugin is failing to render in new Scenes architecture

[bfmatei]

Describe the bug
After the migration of core dashboards to the Scenes architecture, we got an escalation regarding some issues with the Zabbix plugin.

The issue is pretty simple: the plugin is doing a caching by stringifing a set of arguments among which is the request. Unlike in the previous implementation, in the current one the request contains circular references and it can't be stringified without using a circular reference removal (my go-to solution to this) or by manually removing the complex objects from the request object.

Expected behavior
The plugin should not fail.
