Adding trailing / to a KairosDB datasource URL breaks

[bergquist]

If you add a URL like:

http://example.com/

As your datasource URL for KairosDB it won't work.

The datasource URL includes two / characters in a row.

This results in a 404.

The 404 doesn't include CORS headers so then you get errors about CORS.

This confused me and I spent like 20 minutes trying to debug CORS issues.

Maybe add a lib so that building URLs doesn't ever generate this type of bug?
