Create ceph directories in config-download without become

Given how config-download runs in the main branch it's no longer
necessary to use become when creating the work directories for
ceph-ansible to be executed or when running the tripleo_ceph_client
role. Using become introduces the bug this change resolves. Also,
as we are not using become we won't set the owner of the directory.
Instead we will use the default owner of whoever created the directory.
