Feature: Allow to pass custom data to the dialogflow query

[herrlegno]

Description

This pull request makes possible to inject data into dialogflow query.

Context

This PR tries to add a way to inject data into the dialogflow query, an example is adding custom data to the payload object inside queryParams (dialogflow query reference).

Approach taken / Explain the design

Right know, the options object assumes that the only options that it could receive is credentials. So in order to add more options I isolate this credentials inside its own object, and add a new queryData entry to the options object.

Note: this aproach breaks backwards compatibility.

To document / Usage example

Plugin definition:

{
  id: 'dialogflow',
  resolve: require('@botonic/plugin-dialogflow'),
  options: {
    credentials: {
      type: '',
      project_id: '',
      private_key_id: '',
      private_key: '',
      client_email: '',
      client_id: '',
      auth_uri: '',
      token_uri: '',
      auth_provider_x509_cert_url: '',
      client_x509_cert_url: '',
    },
    queryData: {
      queryParams: {
        payload: {
          source: "botonic"
        }
      }
    },
  },
}

Testing

The pull request modifies current tests to adapt to this new structure.

Looks good to me!

The ESLint should be forcing en empty line here IMO. Something to be reviewed in the project
