The security-guide has moved from openstack-manuals repo to the
security-doc repository.
Add the usual manual gating jobs for the security-doc repository.
The guide is translated into Japanese, so publish the Japanese
document as well. This needs a new job 'security-doc-{lang}'.
Add all jobs to Zuul for execution.
Change also translation scripts, the security-guide document is on
top-level of the repository and not below doc. Thus, we need to special
case it.
