Show an opt-in / opt-out option to the user depending on the cluster configuration

As a user, I want to opt-in or opt-out from the telemetry.

If the cluster prefers opt-in or opt-out should be configable via SERVER_FLAGS.

Acceptance Criteria

1. Prompt user to opt in to sending telemetry to Red Hat
2. Prompt should include link to official RH doc about data collection, privacy, and processing.
3. Provide settings in user preferences to opt out of sending telemetry
4. Ensure that NO data are send to the server before the user opt-in or after opt-out.
