Merge pull request #237 from apenney/backwards-compat

Add compatibility classes to handle the backwards incompatible changes.
Support Fedora's rolling development "release", Rawhide

Since Rawhide is a rolling kind of release with no version numbers,
the operatingsystemrelease will actually return "Rawhide" instead
of any Integer. So we better check whether operatingsystemrelease
is an Integer before comparing numbers and cover Rawhide, too.

Rename and refactor database to mysql_database.

Add collate as a new managable parameter, and extend self.instances to
add in all parameters when checking existing databases.  It also adds
self.prefetch in order to speed up Puppet runs.

Provider is also switched to using mk_resource_methods to generate
all the resource readers, and exists? and other methods now use the
property_hash where appropriate.

Tests rewritten to handle changes and extend code coverage.
Rename and refactor database_user to mysql_user.

This work adds max_connections_per_hour, max_queries_per_hour, and
max_updates_per_hour support to the provider and extends self.instances to add
in the new parameters when checking existing users.  It also adds
self.prefetch in order to speed up Puppet runs.
