ohai-solo as a sysinfo provider

Satori should provide a module that will allow it to perform cross-platform data plane discovery through ohai-solo, adhering to the System Info Proposal implementation. ohai-solo is a package used to examine individual host machines and return JSON output of its results.

Requirements

In order to be ohai-solo capable, the ohai-solo module must to automate the following, for any discovered system:

  1. Request and understand package information from ohai-solo's upstream package archive
  2. Determine enough remote platform info to be able to select the correct ohai-solo package
  3. Download the package (probably using wget)
  4. Perform an install of the package
  5. Check the version of an existing ohai-solo package
  6. Update ohai-solo if needed
  7. Uninstall ohai-solo
  8. Gracefully handle any common errors when running ohai-solo
  9. Return the JSON output from ohai-solo as a python dictionary

(Implementations for the requirements in this spec will leverage satori's ssh module.)
