  Incorrect insights.components.rhel_version module doc
  The [example](https://github.com/RedHatInsights/insights-core/blob/master/insights/components/rhel_version.py#L17) in the insights.components.rhel_version pydoc doesn't work. The objects don't have a `rhel_version` attribute.

  5 The ``IsRhel*`` components each use the ``RedhatRelease`` combiner to
  6 retrieve the RHEL version information.
  7 Each component checks if the release version matches the version it represents,
  8 if the version does not match what is expected the class raises ``SkipComponent``
  9 so that the dependent component will not fire.
  10 Can be added as a dependency of a parser so that the parser only fires if the
  11 ``IsRhel*`` dependency is met.
