scenario003/xenial: disable trove

Trove Taskmanager is failing to start quite often, it's probably a bug
somewhere but in the meantime we find it, let's disable its testing.

This is part of this work:
https://etherpad.openstack.org/p/puppet-openstack-xenial
Where we have a list of blockers and workarounds, until things get
stable.
