Remove check-dg-tempest-*

These jobs exist to test proposed changes to the devstack-gate
rexec system.  This system was created to make devstack-gate
self-testing because at the time, the only logic to correctly
check out a proposed commit for devstack-gate existed within
devstack-gate itself.  Since I512203f35797837e1f4612add05f60b759a6eb07
we rely on zuul-cloner to check out devstack-gate prior to running,
thus any changes to devstack-gate will be included by zuul in the ref
that zuul-cloner checks out.

Therefore, both the rexec system in devstack-gate and the jobs
that exercised it explicitly are no longer required.
