Some tempest tests did not configure the host_routes correctly. This would result in a exception from the plugin when trying to access the destination IP for host routes. This also skips tests that are problematic: 1. no agents 2. only can create one subnet per network A luta continua!! Change-Id: Ie8732c08f362db3b8fdbe552db46f26b73ac3422
