Adds ConnectedWorkspacesSettings configuration block (#27820)

* Adds ServerFederationSettings configuration block

The Server Federation related configuration properties were located in
the `ExperimentalSettings` config block. Now that the feature is going
to get out of beta, and foreseeing more configuration properties being
added to it, we're moving them to a block of its own.

If the properties were set in the old location, their values should be
carried over to the new ones. The old properties are left in place and
marked as deprecated not to cause issues with the model.

* Update System Console to include Server Federation section

* Remove system console section

* Move the configuration properties to ConnectedWorkspaces

* Add ConnectedWorkspacesSettings to the telemetry
