This is a major change to the module and would be released as a new
version.
* Add self.instances to database and database_user for puppet resource.
* Update database provider to use flush method.
* Update module to conform to puppet-lint recommendations.
* Cleanup some unecessary logic in mysql::db define type.
* Move mysql_restart to config class.
* Use class to class dependency instead of resource dependency.
* Change appropriate rspec-puppet tests.
* Add fixtures directory to simplify testing.
* Update raketask and spec_helper to reflect fixture changes.
* Update mysql_password function to support validation.
* Move client installation to a separate class.
* Update documentation and readme.
These were missing from the list of allowed privileges:
* event_priv
* trigger_priv
No rspec changes, as we don't even have basic coverage on these providers and
its a minor change so should be low risk.
