Implement the API

[EmreY]

API establishes the communication between the backend (mainly bash scripts) and the frontend (Web GUI). Security restrictions should be applied while implementing this API since this API will enable managing (starting, stopping etc.) WMs through the Web GUI.

This API will enable:

• Getting current loaded topology.
• Getting saved topology list.
• Loading and executing a topology from a conf file.
• Closing a currently active topology.
• Saving a topology (feasibility of the topology should be checked).
• Getting VM details (assigned CPU, RAM, HDD etc.)
• Getting VM usage statistics (CPU, RAM, HDD etc.)
