hadouken

This ansible role collects information about hardware and software from Linux servers, then inserts this information on a sqlite3 database.

The process happens in three phases.

• Distribute and execute hadouken.py
• Collect the json file that hadouken.py generates
• Execute update-db.py to load json info in the database

I also included commands that collects information about EMC Storage, Veritas InfoScale and Cluster Server.
