Control updater's communication with the Experimentation and Configuration Service

In Microsoft Edge Update, the Experimentation and Configuration Service is used to deploy experimentation and configuration payloads. Experimentation payload consists of a list of early-in-development features that Microsoft is enabling for testing and feedback. Configuration payload consists of a list of recommended settings that Microsoft wants to deploy to optimize the user experience. If you set this policy to 'FullMode' (1), the full payload is downloaded from the Experimentation and Configuration Service. This includes both the experimentation and configuration payloads. If you set this policy to 'ConfigurationsOnlyMode' (2), only the configuration payload is downloaded. If you set this policy to 'RestrictedMode' (0), communication with the Experimentation and Configuration Service is stopped completely. If you don't configure this policy, on a managed device the behavior is the same as policy 'ConfigurationsOnlyMode'. If you don't configure this policy, on a device that isn't managed through domain policy or device management, the behavior is the same as policy 'FullMode'.
