Change the yum repository URL in the new recursor custom resource

[jmauro]

Hello everyone,

On your current implementation for the resource pdns_recursor_install there is no way to change the PowerDNS repositories. In our use case, we tend to mirror all our dependencies, so it would sweet to have this feature.

The same would go the pdns_authoritative_install.

Regards,
JM

This looks a useful feature, I'l take a look at both PR's and will look for merging them.

Closing as #73 was not implemented due to cookbook refactors.

As the install resource uses base chef resources it is possible to implement a custom repository using a wrapper cookbook while still leveraging the config and service resources provided by the pdns cookbook.
