- Orchestrator interaction with the network driver is limited
to at most allocation/release of simple resources. For local scope

full driver code base does not need to be pulled into the orschestrator.
This PR introduces a dedicated package in each builtin nw
driver for that purpose, as it was done for overlay driver.
