Support both R and S+ in NetworkFactory
NetworkFactory needs to be backwards compatible as
it is statically linked by the Wifi module, which
needs to run on both R and S.
To achieve this, maintain 2 separate implementations
called NetworkFactoryImpl (S+) and
NetworkFactoryLegacyImpl (R). NetworkFactory itself
becomes a shim that delegates to one of these
implementations depending on the device's SDK version.
