Change endpoint to wc-telemetry/tracker

Since this endpoint isn't a publicly documented endpoint, we'll keep it
out of the wc/v3 namespace. Instead we're introducing a new wc-telemetry
namespace. The name of the endpoint then is updating to tracker.

The wc-telemetry endpoint is unversioned for consistency with
wc-analytics and because it's not publicly documented.
