As system, I provide a REST API endpoint to import tests

Users must be able to use the Xray REST API to import test cases in JSON format.

The JSON format will be the following:

[
	{
		"summary": "My new Test Case",
		"description": "Desc",
                "project": { "id": "123"},  // "project": { "key": "CALC"}
		(...)
		"xray_testtype": "Manual",
		"xray_steps": [
			{
				"step":"Step 1",
				"data":"Data for Step 1",
				"result":"Result for Steps 1"
			},
			{
				"step":"Step 2"
			},
			{
				"step":"Step 3",
				"data":"Data for Step 3"
			},
			{
				"step":"Step 4",
				"result":"Result for Step 4"
			}
		],
		"xray_gherkin_def": "",
		"xray_unstructured_def": ""
	}
]

All issue fields must be supported and the schema should be the same as found here: /rest/api/2/issue/bulk.

The Xray fields can be prefixed with "xray_" to disambiguate possible duplicated in Jira. This is optional. This means fields can just be referenced by "steps", "testType".

The REST API endpoints should be:
/api/v1/import/test/bulk[?project=<id|projectKey>]
/api/v1/import/test/bulk/{jobId}/status 

The project can either be specified as a query parameter or it can be specified on individual test level; project specified at test level will override the value specified, if specified, using the query parameter
