Adding the tripleo repositories to PROJECTS

Adding the tripleo repositories here so that the correct revisions are
then cloned into /opt/stack/new for use by tripleo-ci/toci_gate_test.sh

This along with setting TRIPLEO_ROOT to /opt/stack/new should ensure the
correct version of each repository will be used in ci. DIB_REPOLOCATION_*
is currently being used to point disk_image_builder to these
repositories also.
