(#19) Update vmfloaty to expect /api/v1 in URL for disk endpoint

This commit updates floaty to use a new endpoint to modify vms. Now you
can use the modify command to extend the disk space of a given vm. The
downside is this new endpoint only exists at /api/v1 on the pooler, and
the way Faraday works required an update to removing a leading slash for
each request endpoint. Users should update their URL in the floaty dot
file to include a /api/v1 at the end of the pooler url
