Add ovsdbapp to PROJECTS
This patch is adding ovsdbapp to the $PROJECTS variable so it can be
installed from git, without it the job fails with:
The /opt/stack/new/ovsdbapp project was not found; if this is a gate job,
add the project to the $PROJECTS variable in the job definition.
# our project repository. This makes zuul do the right
# reference magic for testing changes.
export PROJECTS="openstack/networking-ovn $PROJECTS"
+ export PROJECTS="openstack/ovsdbapp $PROJECTS"
# Keep localrc to be able to set some vars in pre_test_hook
export KEEP_LOCALRC=1
