Daniel P. Berrangé 34ed46a284 gitlab: add a CI job to validate the DCO sign off
While checkpatch.pl can validate DCO sign off that job must always be
advisory only since it is expected that certain patches will fail some
code style rules.

We require the DCO sign off to be mandatory for all commits though, so
it benefits from being validated in a standalone job.

This can be achieved by passing the "-s" flag to the "git commit" command.
To bulk update all commits on current branch "git rebase" can be used:
