Andrea Frittoli (andreaf) 290d9d87f4 Use stage_dir instead of /opt/stack
Historically we have collected devstack logs under /opt/stack.
Stop doing that and collect them in the stage_dir instead, so that
once the base job logs pull service comes around we are ready for it.

This add the benefit of writing things into a folder which is
already owned by the ansible user (ansible_user_dir), so we don't
run into issue writing there.

A few logs (devstack log, log summary and dstat) use to show up on
logs.o.o. just because they happened to already be in /opt/stack/logs.
With this change they would be lost, so adding them to post.yaml.

Export journal files from devstack services
Export the systemd journal for every devstack service in native
journal format as well as text. Also, export a syslog-style file with

Writes the output to the ``logs/`` subdirectory of
``stage_dir``.
