[all PATCH v2] gitlab: add CI job for validating DCO signoff

[Daniel P. Berrangé]

This job uses the shared "check-dco" image to validate that all
commits on a branch in a developer's repo fork have a suitable
Signed-off-by statement present.

Signed-off-by: Daniel P. Berrangé <berrange at redhat.com>

This patch was against the Perl repo, but if this is approved then
I'll also apply it to *all* the other repos which currently lack a
DCO check, without reposting further patches for each repo.

For libvirt.git I'll send a patch to update its existing DCO job.

Changed in v2:

 - Exclude based on project namespace, not branch names
