Convert nwfilter ebiptablesAllTeardown to virFirewall

Browse Source 
Convert the nwfilter ebiptablesAllTeardown method to use the
virFirewall object APIs instead of creating shell scripts
using virBuffer APIs. This provides a performance improvement
through allowing direct use of firewalld dbus APIs and will
facilitate automated testing.
