Change default port values to strings, as expected by datadog.conf.erb

[Dvanderspuij]

If the port variables are not defined, puppet will fail on parsing the template.

Error when parsing template

+1, I ran into this with 1.5.0

I also ran into this in 1.5.0, I was able to get around it by just overriding the defaults in my wrapper class to be strings (still using default values) if anyone else is looking for a fix until this is merged.

Thanks for this @Dvanderspuij , we identified the root cause and addressed it with 6244659 in PR #161

This should be sorted in our next release! :)
