CODE TESTING:
=============
1. Start RestServer: python RestServer.py

2. Try curl commands (case no secured REST: http & no authentication):

- Request to execute playbook:
curl -H "Content-type: application/json" -X POST -d '{"Id": "10", "PlaybookName": "ansible_sleep", "NodeList": ["host"], "Timeout": "60", "EnvParameters": {"Sleep": "10"}}' http://0.0.0.0:8000/Dispatch

response: {"ExpectedDuration": "60sec", "StatusMessage": "PENDING", "StatusCode": 100}

- Get results (blocked until test finished):
curl --cacert ~/SshKey/fusion_eric-vm_cert.pem --user "appc:abc123" -H "Content-type: application/json" -X GET  "http://0.0.0.0:8000/Dispatch/?Id=10&Type=GetResult"

response: {"Results": {"localhost": {"GroupName": "host", "StatusMessage": "SUCCESS", "StatusCode": 200}}, "PlaybookName": "ansible_sleep", "Version": "0.00", "Duration": "11.261794", "StatusMessage": "FINISHED", "StatusCode": 200}

- Delete playbook execution information
curl --cacert ~/SshKey/fusion_eric-vm_cert.pem --user "appc:abc123" -H "Content-type: application/json" -X DELETE  http://0.0.0.0:8000/Dispatch/?Id=10

response: {"StatusMessage": "PLAYBOOK EXECUTION RECORDS DELETED", "StatusCode": 200}
