Define TcpSocketMonitor with a single dump method
This patch adds a TcpSocketMonitor registered in Controllers and
implementing a single dump method for pretty printing socket info
dumped with SockDiag for all sockets on the system.
The dump method can be called with
$ adb shell dumpsys netd tcp_socket_info
Example of output is:
