Jiri Stransky 248099db8c Fix race conditions between containers
In many occasions we had log directory initialization containers
without `detach: false`, which didn't guarantee that they'll finish
before the container depending on them will start using the log
directory.

This is now fixed by moving the initialization container one global
step earlier, so that we can keep the concurrency when creating the
log dirs. (Using `detach: false` makes paunch handle just one
container at a time, and as such it can have negative performance
impact.)

For services which have their container(s) starting in step_1,
initialization cannot be moved to an earlier step, so the solution
here was to just add `detach: false`.

As a minor related change, cinder DB sync container now mounts the log
directory from host to put cinder-manage.log into the expected
location.
