The deployments.yaml tasks file is not specific to roles, it's the same
for all. Moving it to the top level config-dir directory will allow
parallelizing these tasks across all roles instead of doing the roles
one by one.
For the time being, it's also copied to the existing location under the
role specific dir for backwards compatibility so that this patch can
merge without initially breaking tripleo-heat-templates. See the related
tripleo-heat-templates patch:
