This patch removes static methods for logging IP connectivity events defined in android.net.metrics and replaces them with a single log() instance method defined on IpConnectivityLog. Event constructors are now public also. Every classes logging such events now create an instance of IpConnectivityLog for logging event objects directly instantiated with new. Removing static dependencies allow straightforward testing of logging. This patch also removes the base IpConnectivityEvent class which is not needed any more.
