[NET-493] - Additional data fields to send to account management (#2583)

* Send relays and internet gws count to amb

* Unify usage funcs in logic pkg

* Fix ee build

* Revert "Unify usage funcs in logic pkg"

This reverts commit 28afc91f7e.

* Add more resource metrics on getUsage handler

* Use pro module's function to get server usage on lic val

* Move GetRelays to pro package
