On Re-run, prometheus directory exists and the run fails
with mkdir: cannot create directory ‘/etc/prometheus’: File exists.
Or when we use sg_core plugin with their prothemeus config file,
It also creates prometheus config directory. Then again prometheus
devstack plugin fails with same error.
In order to fix it, use mkdir -p while creating prometheus directory.
It will ignore error if parent exists.
