the options [connector,hostname, etc.] is not supported

[UzverNumber47]

mongodb.connect method accepts 3 arguments url, options and callback. In the connect method of the module settings object is passed as options. So some of the fields are not supported by mongodb client.

Settings is something that loopback passes from datasources.[env].json when creating a datasource.
Maybe it's a good idea to pass settings.options instead of the entire object to mongodb.connect?
In datasources.[env].json:

"storage": {
    "name": "storage",
    "connector": "loopback-component-storage-mongo",
    "host": "127.0.0.1",
    "database": "test",
    "port": 27017,
    "options": {
       "mongoConnectionOption1": "value"
    }
  }

connect: (callback) ->
    self = @
    if @db
      process.nextTick ->
        if callback
          callback null, self.db
    else
      mongodb.MongoClient.connect @settings.url, @settings.options, (err, db) ->
        if not err
          debug 'Mongo connection established: ' + self.settings.url
          self.db = db
        if callback
          callback err, db

Annoying warning:
the options [connector] is not supported
the options [hostname] is not supported
the options [port] is not supported
the options [debug] is not supported
the options [url] is not supported
