Switch tap-as-a-service-tempest-plugin to ML2/OVS

It also changes x/tap-as-a-service to openstack/tap-as-a-service
in the list of required projects as TaaS is now official OpenStack
project and part of the Neutron stadium.

Additionally this patch removes
networking-midonet-tempest-aio-ml2-full-centos-7 from the check queue as
that midonet job is not existing anymore.
