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.ohaisolois a package used to examine individual host machines and return JSON output of its results.
Requirements
In order to be ohai-solo capable, it needs to automate the following, for any discovered system :
- Request and understand package information from ohai-solo's upstream package archive
- Determine enough remote platform info to be able to select the correct ohai-solo package
- Download the package (probably using wget)
- Perform an install of the package
- Check the version of an existing ohai-solo package
- Update ohai-solo if needed
- Uninstall ohai-solo
- Gracefully handle any common errors when running ohai-solo
- Return the JSON output from ohai-solo as a python dictionary

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