Support example responses in generator

[jlengrand]

Postman supports example responses to illustrate the result of queries without having to hit an actual server.

#63 adds support for those examples.

What still needs to be supported :

• Support for example responses for GET requests (will be done as part of Support example responses for GET requests #78)
• When no response is present for POST requests, a response array is still added

• No support for multiple example responses at the moment.
• Better unit testing is necessary
• Responses contain the original request information (see comment below) (works now, but generated headers and auth info are missing. Asked postman team for more info).

I also note that when I look at already existing and validated postman collections, they seem to be repeating information about the request as part of the response, which allows to show the actual request as part of the response.

This isn't the case for ours at the moment

This is how the response looks like in this case :

					"response": [
						{
							"name": "successful operation",
							"originalRequest": {
								"method": "POST",
								"header": [
									{
										"description": "Added as a part of security scheme: apikey",
										"key": "x-api-key",
										"value": "<API Key>"
									},
									{
										"key": "Accept",
										"value": "application/json"
									}
								],
								"body": {
									"mode": "raw",
									"raw": "{\n  \"From\": \"2020-12-31T22:59:59+00:00\",\n  \"To\": \"2020-12-31T22:59:59+00:00\",\n  \"Tags\": [\n    \"<string>\",\n    \"<string>\"\n  ]\n}",
									"options": {
										"raw": {
											"language": "json"
										}
									}
								},
								"url": {
									"raw": "{{baseUrl}}/calculate/jobScheduler",
									"host": [
										"{{baseUrl}}"
									],
									"path": [
										"calculate",
										"jobScheduler"
									]
								}
							},
							"status": "OK",
							"code": 200,
							"_postman_previewlanguage": "json",
							"header": [
								{
									"key": "Content-Type",
									"value": "application/json"
								}
							],
							"cookie": [],
							"body": "[\n  {\n    \"JobId\": \"voluptate minim aliquip veniam\",\n    \"Count\": 65382380,\n    \"Items\": \"aliqua aute\"\n  },\n  {\n    \"JobId\": \"et sunt est sit\",\n    \"Count\": -71167171,\n    \"Items\": \"voluptate\"\n  }\n]"
						}
					]

Current creation process generates this for CheckoutService v71 : https://adyendev.postman.co/workspace/New-Team-Workspace~6c06bed3-d57a-4e9a-a3b1-8f4f9fc34ab1/collection/25716836-32417912-96bb-4e86-a1c0-310f7d02e0a7?action=share&creator=25716836

• Add response headers (added ugly postman flag instead)
