Update ioos_btn_metrics.csv

closes #99

The test failed, but I don't think it's because the update to the csv is bad. I think pkg_resources has been deprecated?

That is just a warning. And it is in a downstream library, just ignore it.

The real failure is above in the log. The test_ngdac_gliders_fast is failing with a 503. It is likely that the server blocked the request and/or is under maintenance. Let's restart the tests later just to be sure.

Test no longer fails! Merging.
