Add toggleable debug / error trace for Clients EvalJavascript

User Story

As an developer, I may not be able to monitor user environment to retrieve errors so that I can debug client-side errors.

If the end-user is not available to check console (if I do not have access to the client to check console) and report error message and stacktrace, I want to be able to retrieve error details from client-side and log it at server-side.

Acceptance Criteria

Can toggle on/off the ability to receive error logs from scripts executed with Clients.EvalJavascript
