Assertions using json schema v3 or v4

AC1:
GIVEN-The JSON `schema` of the API response
WHEN-I assert the API response using the schema with version as parameter
THEN-I should be able to get the desired result as PASS or FAIL to determine the test status.
AND-If failed, it should display or log(WARN or ERROR level) list the failure reasons in a pretty format.

AC2:
Have mechanism to pass the Schema file for the API response in the DSL.

Note:
"responseSchema" : (* new field which you can introduce) : Keep it optional. If supplied by the user, only then validate against it(the "body" of the response).

I think only the "body" should match the Schema definition, right?
Definitely not the "status" I mean. Have a look at the Schema definition file.
If yes, then implement the field as "responseBodySchema" (instead of "responseSchema")

Example:
```JSON
{
...
...
"responseSchema": {
"schemaPath": "path/to/schema/file",
"schemaVersion": "W3 Version? 3.0 or 4.0" //<--- optional (assign a default value if not supplied by user)
},
"verify": {
"status": 200,
"body": {
"login": "octocat",
"id": 583231,
"type": "User"
}
}
}
```

AC3: (Future purpose - Implement via a new ticket if there is a Usecase for this, otherwise not needed now as AC2 shd cover most usecases)
GIVEN-I want to assert the API response using a given `schema` of v3 or v4(parameterised)
WHEN-I receive the API response
THEN-I should be able to get the desired result as PASS or FAIL to determine the test status
