The tripleo-ansible role tripleo_ceph_work_dir will manage that
directory for you (recreate it when needed to reflect what is in
Heat). It is run when config-download is run.

If there is no stack, the stack will be created when you deploy and
config-download's directory of playbooks will also be recreated. You
shouldn't need to worry about cleaning up the existing config-download
directory. You can, but you don't have to.
