Settings and SystemUI use these through raw AIDL calls.
Make them proper manager calls so we can move the implementation
without touching the callers again.
For now these still call into ConnectivityService via
IConnectivityManager. In an upcoming CL the implementation will
move to VpnManagerService.

Files that are planned to be part of the connectivity module are grouped
in packages/Connectivity, so they can be built separately and moved in
one operation with their history into packages/modules/Connectivity.
This places the files in the existing framework-connectivity-sources
filegroup instead of the current framework-core-sources filegroup. Both
are used the same way in framework-non-updatable-sources.
