Do not change NetworkInfo.DetailedState.

I'd changed DetailedState to force ConnectivityService to treat
provisioning apn's specially. In particular so that they wouldn't
be identified they were fully connected until the provisioning
actually started. The problem is that DetailedState is a public enum
that has a CTS test and just changing the CTS to allow for the new
state (CONNECTED_TO_PROVISIONING_NETWORK) was inappropriate.

Instead I've added a new mIsConnectedToProvisioningNetwork variable
and used the DetailedState.SUSPENDED as the intermediate state.
