Added node parameter to data in Catalog register

[hreidar]

This is done so the API properly passes node_meta data to Consul. PR #222 did not fix this issue. Consul appears to want node_meta in the data body not params.

I am not sure about the exact mechanisms behind the consul server. Should we remove the node_meta addition to params and only add it to the data body?

Not sure why the tests are failing, just added one line ;-)

I'd love to see this fixed and merged, this fixed my issue and let me update NodeMeta and start testing with consul-esm

No interest in fixing this? I don't believe the checks are failing because of my code additions.
