Add OTADM feature for Verizon requirement.

- GsmDataConnectionTracker.java
  <in function createApnList>
  : modify parameter type for new ApnSetting.
    (carrierEnabled has changed to boolean from integer,
     BEARER has changed to integer from string).
  <in function createAllApnList>
  : modify telephony db query statement using carrierEnabled. (carrier_enabled: 1 enable apn, 0: disabled apn)
  <in function buildWaitingApns>
  : modify apn management code when current RAT (radio access technology) is LTE or EHRPD.
    add internal function named needToCheckApnBearer to check current RAT is LTE or EHRPD.
- ApnSetting.java
  : add two member variable (carrierEnabled: apn enable/disable , bearer : Radio Access Technology)
- Telephony.java
  : add two static string CARRIER_ENABLED & BEARER.
- ApnSettingTest.java
  : add two assertEquals in function assertApnSettingEqual.
    add CARRIER_ENABLED & BEARER parameters.
