Fixed several data issues

1. Added workaround for changing immutable capabilities
   until connectivity service supports it.
2. Fixed that logging tag suffix after transport changed.
3. Port VCN code from old data stack.
4. Fixed some cases that we need to tear down the underlying
   networks, but also inform data network controller of
   data setup fails, for example, no live network request
   or VCN requested tear down before creating the agent.
5. Fixed the incorrect link status report.
6. Attach/Detach network requests after network capabilities
   changed.
7. Support the legacy permanent fail cause carrier config.
