Refine NetworkCallbackTest

In R, to avoid data overages due to apps not detecting a
meteredness change, when a wifi network changes from unmetered
to metered the network will go down and will be replaced with a
new network. It will make NetworkCallbackTest fail because the
original design is getting the active network in setUp(). So once
the wifi reconnects, the network which is got in setUp() will be
meaningless and make the test fail due to network mismatches.
The new changes are:
1. Moving some initial pre-configurations into setUp().
2. Override the onCapabilitiesChanged() to check if network has
   changed to metered or not.
3. Add unregisterNetworkCallback() into iMyService.aidl so that
   NetworkCallbackTest can call it to unregister the network
   callback.
4. Enlarge the timeout of connecting network and receiving
   callback to prevent network cannot reconnect in time or
   callback cannot be received in a short time.
