Add setLanguage Network calls

* Add OSRequestUpdateLanguage to Requests implementation
* Add setLanguage method to OSUserStateSynchronizer, OSUserStateSMSSynchronizer and OSUserStateEmailSynchronizer using SMSAuthHashToken and EmailAuthHashToken
* Add updateLanguage method to OSStateSynchronizer that retrieves channelId from userStateSynchronizer and executes simultaneous requests
