Ids generator

[hector-js]

Is your feature request related to a problem? Please describe.
The user wants to create a scenario adding some identifiers in the command line. At this moment this task must be done manually.

Describe the solution you'd like
Given a user wants to generate a scenario for the following endpoint /customers/{id}/product?name={param1}&lastname={param2} adding the identifiers id, param1 and param2 in the command line. When the user execute the following line of code:

hjs g g "customers/{id}/product?name={param1}&lastname={param2}" --id 1 --name mateo --lastname smith

Then the user shoud have in the resourse file the following scenario:

{
  "_get": {
    "/customers/{id}/product?name={param1}&lastname={param2}": [
      {
        "_req": {
          "_id": 1,
          "_param1": "mateo",
          "_param2": "smith"
        },
        "_res": {
          "_body": {
            "Ok": "to be defined"
          }
        }
      }
    ]
  }
}

Also, it should generate the test adding the ids.
