Remove old openstack/js-openstack-lib jobs
Remove old openstack/js-openstack-lib jobs

Legacy jobs are failing and block gating.
The other jobs are using legacy nodejs which is not
of interest either.
The plan is to move all job definitions into the
deliverable repository and port them to Zuul v3 format
and current nodejs (10, 12).
