Data connection for carrier specific APN

Implement the following features to support carrier network connection.

1. Sets default preferred APN
   Customize a preferred APN which is used on the first boot. Because
   some operators specify the APN to use by default if the preferred
   APN is not set. So, make it possible that specify the default
   preferred APN by CarrierConfig.

2. Does not use dun apn in roaming network
   Some operators does not use dun apn for the tethering data
   connection in roaming networks. So, make it possible that to not
   use dun apn in roaming network.

3. Uses only preferred APN set
   Some operators does not want to use anything other than preferred
   APN automatically even if the connection fails to access network.
   So, make it possible that to use only APNs with the same set id as
   preferred APN.
