Try to use CloudSim

[slivingston]

The OSRF has made substantial progress on CloudSim, including restarting their main repository last year. As such, I recommend that we try to use it for managing simulations during fmrbenchmark competitions. Also, consider forking or using fragments of it for one-time evaluations of controllers (in general, not necessarily during official competitions). URLs for beginning:

• https://bitbucket.org/osrf/cloudsim
• https://bitbucket.org/osrf/cloudsim/wiki/Home

Work here might overlap with that for #12

the talk at ROSCon 2016 by Ian Chen (video and slides) provides more details about progress on CloudSim. it is also described as part of a talk about the NASA Space Robotics Challenge at ROSCon 2017.

project appears to not be active. source repositories were moved to GitHub and marked as "archived" by the owner, e.g., https://github.com/osrf/cloudsim

since this issue was opened, I have more experience in running Gazebo simulations headless and also managing user sessions on websites, user file uploads, etc., so I think that we can make a solution specific for the goals of our project here.

regarding OSRF and simulations, here is a nice post about plans and current work: https://discourse.ros.org/t/the-future-of-ros-simulation-2025/11538/5
