README and repo organization

[boxrhcp]

Task

Detailed Description

The repo is accumulating scripts and the README needs to be updated accordingly.
The README should include not only the directory map of the repo but also the installation and execution instructions. It must also explain every value in the json config file and list every dependency used.
The repo structure should be reorganized to be more descriptive, specifically follow the modular organization.
Inside bin we should have the following:
main.py
sut/ - with all the SUT deployment automation scripts and files needed
workload/ - with all the workload (caliper) scripts and configuration files needed
analyzer/ - with all the aggregator scripts and possible scripts that deal with reading results.

This organization needs to change correctly every path that is written in every script or errors will appear.

Acceptance Criteria

• The tool is running without any errors

• The README is clear and describes all the information requested in the task
