This change adds UMA tracking for SMSReceiver API to give us data on
the how long an SMS takes to be delievered and how long a developer expects
the sms to be delievered. Specifically it will track the following:

1. Duration from when the API is called to when an SMS is
   successfully received.

2. Timeout value specified when the API is called.
