sample-generator: Improve YAML output

This commit makes the following minor improvements
in YAML output of oslopolicy-sample-generator.

* Add a blank line between policies.
  Previously when a deprecated rule exists there was no blank line
  between the deprecated rule and the next rule.
  It was not easy to identify the beginning of the next rule.
* Drop unnecessary blank line comment.
  If a policy is defined by RuleDefault instead of DocumentedRuleDefault
  there is no description and unnecessary blank line comment was added
  in an output YAML file.
* Honor newlines in deprecated_text.
  Previously newlines in deprecated_text were dropped by
  _format_help_text(). Main deprecation message and reason are
  processed separately and newlines are not dropped now.
