[Feature]: Extend Namespaces to User Modules

[Grant-Archibald-MS]

Is your feature request related to a problem? Please describe.

Namespaces apply to function modules not user modules. To implement the ring deployment model, the user MEF modules should expose a list of Namespaces.

Describe the solution you'd like

Proposed Solution

• The provider should expose a list of Namespaces.
• The namespaces should be checked against Test Settings to verify that the namespace is in the allow list.
• If the namespace is not in the allow list, the provider should not be loaded.

Implementation

• Update the provider to include a method that returns a list of Namespaces.
• Check the returned namespaces against the Test Settings allow list.
• Prevent loading of the provider if any namespace is not in the allow list.
• Move Environment and BrowserContext to Deprecated
• Release Build should Deny Deprecated namespace
