Move Ruby code to Python

[osrf-migration]

Original report (archived issue) by Andrés Fortier (Bitbucket: andres_fortier).

Girder provides a client implemented in python (girder-cli) which already defines all the interactions with a Girder server. To avoid re-writing most of that we should migrate our ruby implementation of the commands to python, so it just becomes a thin wrapper around the existing libraries.

Is there a girder C or C++ api? The C++ library would need to support both fuel and Girder anyways, so I think it makes sense to implement it in C++ and call those functions from Ruby rather than also writing it in python.

Not that I'm aware of. Note however that this issue was created back in the days were the main development focus was going to be placed in Girder, so now that we are shifting our attention to the custom backend this decision may not be the best. @caguero should we close / rephrase this one?

I believe we're not considering Girder any more, so closing this.
