Initialize the monitoring.

@example Create the new monitoring.

  Monitoring.new(:monitoring => true)

@param [ Hash ] options Options. Client constructor forwards its

  options to Monitoring constructor, although Monitoring recognizes
  only a subset of the options recognized by Client.

@option options [ true, false ] :monitoring If false is given, the

  Monitoring instance is initialized without global monitoring event
  subscribers and will not publish SDAM events. Command monitoring events
  will still be published, and the driver will still perform SDAM and
  monitor its cluster in order to perform server selection. Built-in
  driver logging of SDAM events will be disabled because it is
  implemented through SDAM event subscription. Client#subscribe will
  succeed for all event types, but subscribers to SDAM events will
  not be invoked. Values other than false result in default behavior
  which is to perform normal SDAM event publication.
