Do validation properly

Commit 9f416dd25 stopped implicit validation_resources provisioning.
This patch updates our tests to keep in line with tempest's new way of
doing things. We also remove the admin password, since pubkey
authentication is enough, and pass the network parameter to
create_server to make sure we can SSH to it.
