wbatch: elevated privileges for create_hostnet

Browse Source 
Currently, create_hostnet.bat asks no less than six times for elevated
privileges (once for each network created or modified). This change adds
code that allows create_hostnet to keep the elevated privileges while
configuring networks. That is, it prompts once rather than six times.
