Tools: Deployment and TestControl Containers

This patch add containerization of VSPERF support.
The patch facilitates creation of 4 containers:
1. Interactive Deployment
2. Auto Deployment
3. Interactive TestControl
4. Auto TestControl.
The patch also includes a minimal client to work with interactive
containers.
The docs folder provides detailed documentation.
Fixed pylint errors in libs folder.
Removed proto built python files, and added the build process in
prepare.sh.
Stability improvements for Auto versions of deployment and testcontrol.
Enhance client with 'mode' feature, where client can run either to do
only deploy/only test or both.
Add sample configuration file for client
Fixed few typos - as suggested by AL.
