You don't need to explicitly specify newproperty(:provider). There is a default
provider parameter which is added when you create a provider for the type. That
default parameter handles making the provider available via resource.provider
(rather than the usual resource[:provider]), which is how the default ensure
property interacts with it. So currently Puppet doesn't realize your type has a
provider as Puppet understand providers. Other than that, your code looks fine.
Remove the provider property, and it should work.
