Yichen Wang 8a9dda8f7d Use redis as the communication protocol
1. Supported to use redis as the orchestration and reporting protocol;
2. Implemented the agent to run on every testing VM;
3. Modified the HTTP tools to use redis messaging APIs;
4. Added APIs to display provision details for klouds;
5. Added the option to allow a prompt before running tools;
6. Cleanup unneeded code;
