It is not possible to test deps-on changes on repos like heat-agents

[Michele Baldessari]

It would be very useful in tripleo ci to be able to test changes on other repos (For example I needed to test tripleo-ci against a heat-agents change). Spoke to Sagi and it is currently not possible due to:
https://github.com/openstack-infra/project-config/blob/master/jenkins/jobs/tripleo.yaml#L160-L200

an example of a failure when doing this is the following:
http://logs.openstack.org/82/448982/3/check/gate-tripleo-ci-centos-7-undercloud-oooq/5fea6ec/console.html#_2017-03-23_10_59_35_362873

It would be nice if this limit could be either lifted or a bit more clearly documented (ideally with an example tripleo-ci review like the one Sagi showed me here: https://review.openstack.org/#/c/449102/)

    Clone projects if they aren't cloned by ZUUL

    When we build projects in ZUUL_CHANGES we usually have them
    cloned by infra with zuul-cloner in /opt/stack/new with all
    required patches, so we just copy them and build. But sometimes
    we need to build dependencies in projects that are not in PROJECTS
    and not cloned, like heat, glance, etc. This commit supports
    cloning and patching of projects that are not cloned by ZUUL
    initially.
    It was partially implemented in tripleo.sh so we close the gap.
