Remove trailing dot from URL
Remove trailing dot from URL

`bigmler cluster` outputs the URL of the created cluster with a dot at the end.

When clicking the URL from a Jupyter Notebook one reaches the 404 BigML page because of the dot.

This commit just removes the trailing dot so that the URL can be clicked without this problem.
