Add capability to upload multiple files and array of string parameters in one request

[ydhnwb]

Summary

Add capability to upload multiple files in one request and array of string in parameters.

Test Plan

Android only, multiple files upload in one shot via Multipart

Send all the files in files param. In this case path, field & type will be ignored. Example:

const options = {
  url: 'https://myservice.com/path/to/post',
  files: [
    {
      path: 'file://path/to/file%20on%20device.png',
      field: 'uploaded_media'
    }
  ],
  method: 'POST'
}

Note that type will always be multipart when files is passed

Android only, multiple parameters in one shot via Multipart

Send parameters as list of string.

const options = {
  url: 'https://myservice.com/path/to/post',
  files: [
    {
      path: 'file://path/to/file%20on%20device.png',
      field: 'uploaded_media'
    }
  ],
  paramaters: {
    urls: ["https://example.com", "http://example.com"]
  }
  method: 'POST'
}

However, if you pass the array with single value array like ["example.com"], it will be count as string in your backend. It is using request.addArrayParameter("key", List) in native code.
