Data connection for carrier specific APN 

Implement the following features to support carrier network connection.
This commit is to define the carrier config for each features.

1. Sets default preferred APN
2. Uses dun APN when using Preset APN in roaming network

Also, fixed that to use only APNs with the same set id as preferred
APN.
