Revert "turn multi host true for nova network by default"

This reverts commit 2e1a91c50b73ca7f46871d3a906ade93bbcac6a7

It looks like this introduced race bug 1491949 in the
gate-tempest-dsvm-large-ops job causing rpc timeouts when
deallocating network information for an instance,
specifically around the dnsmasq callback to release the
fixed IP that the instance was using which triggers the
disassociation between the fixed IP and the instance in the
nova database.
