Oops, I see this is a duplicate of #38 / #40.

@sl1pm4t Thanks for your PR! You're right this is a dupe. But also, following #46 (and #49) consul_catalog_entry will be deprecated in favor of consul_node and consul_service. We do not currently support node_meta in consul_node, so adding that there would be wonderful if you want to rework the PR with those incoming changes in mind. That would be relatively substantial change for your implementation, but the upstream APIs are the same.

We've just recently released the final 1.* series release (see CHANGELOG) prior to these changes.

Hi @pearkes - in the end I didn't need this change anyway. Thanks!
