Remove temporary fixes in cinder::base

Are the "Temporary fixes" still needed in `cinder::base`?

    # Temporary fixes
    file { ['/var/log/cinder', '/var/lib/cinder']:
      ensure => directory,
      owner  => 'cinder',
      group  => 'cinder',
    }

I don't seem to need these fixes with Ubuntu:
* the folder `/var/lib/cinder` is owned by `cinder:cinder` with mode `0700` and
* the folder `/var/log/cinder` is owned by `cinder:adm` with mode `0750`.
