Extend the meilisearch object with MeiliSearch settings

Description
Currently it is only possible to change the MeiliSearch settings of an index by making an API request to MeiliSearch after a collection type is indexed. It would be nice to extend the MeiliSearch object that was added with the 0.4.0 release with optional MeiliSearch settings.

Basic example
With the 0.4.0 release it is now possible to transform the content-types before inserting them into MeiliSearch by using the following code.

module.exports = {
  meilisearch: {
    transformEntry({ entry, model }) {
      return sanitizeEntity(entry, { model })
    },
  },
}

By adding a settings property it would be possible to update the MeiliSearch settings after a content type gets indexed. For example:

module.exports = {
  meilisearch: {
    transformEntry({ entry, model }) {
      return sanitizeEntity(entry, { model })
    },
    settings: {
      rankingRules: ['typo', 'words', 'proximity', 'attribute', 'wordsPosition', 'exactness', 'desc(release_date)'],
      filterableAttributes: ['genres'],
      distinctAttribute: null,
      searchableAttributes: ['title', 'description', 'genres'],
      displayedAttributes: ['title', 'description', 'genre', 'release_date'],
      stopWords: null,
      synonyms: {
        wolverine: ['xmen', 'logan'],
        logan: ['wolverine', 'xmen']
      }
    }
  },
}

Hey @haye-webbio, if you are willing to contribute it shouln'd be to hard to add:

• Create a function in the collection connector called getSettings
• The same way as the function getIndexName, get the settings from the config file

      const model = models[collection].meilisearch || {}
      const settings = model.settings || {}
// check if settings is an object
// if not return empty {}
    return settings

• In this line, fetch the settings with const settings = collectionConnector.getSettings()
• make a call to MeiliSearch await client.index(indexUid).updateSettings(settings)

And it is done :)

Sure! :)
