Tempest Gate - Update

1. Remove DEVSTACK_GATE_NO_SERVICES since it disables all default services
(see devstack-gate/features.yaml no_services variable.)
2. Remove redundant imports, ceilometer is enabled by default as a service(see 1.) and
 adding AODH project is already done in vitrage.yaml under project-config/jenkins/jobs
