Take a Network parameter to have an one-to-one mapping between
keepalive and its underpinned network on the automatic keepalive.
Existing design could not really tell which network should the
automatic keepalive check for the TCP socket status if there are
multiple automatic keepalives enabled, e.g. Bothe IWLAN and VPN
on WiFi enable the automatic keepalive. The keepalive for IWLAN
should check if there are any TCP sockets on the IWLAN network
instead of VPN network.

registerSystemDefaultNetworkCallback is required by WifiTrackerLib to
detect the system default network for UI purposes. Currently this API is
allowed for holders of the NETWORK_SETTINGS permission, but not
NETWORK_SETUP_WIZARD. Since SUW also uses WifiTrackerLib, we should
allow this API for NETWORK_SETUP_WIZARD as well.

The default TCP polling alarm timer is very large(2 mins).
It's expensive in the CTS to wait for a couple alarms.
The polling alarm should be deprecated soon and replace
with callback design, so add the hidden method for testing
purpose to support the short term usage until design is
replaced with callbacks.
With the hidden method, the alarm timer will decrease to
1 second for a specified time period. The TCP sockets status
could be verified every 1 second.

This patch uses the binder token represented by the callback
to communicate the identity of the AutoOnOffKeepalive through
the alarm mechanism. This is a lot more robust and easy to
understand.
Addressing this, on top of the robustness and readability
advantages, corrects three bugs.
• The |obj| in the message to CMD_MONITOR_AUTOMATIC_KEEPALIVE
is now the binder token both on the sender side and the
receiver side, while the previous code had a Network in the
sender while the receiver expected AutoOnOffKeepalive,
crashing the system server with a wrong cast.
• The intent sent in the alarm would have a yet-uninitialized
value for the slot, so it would not be possible to find the
auto keepalive when the alarm fires.
• When the slot is reassigned, the alarm continued to fire
with the same slot value, so the auto keepalive would no
longer be found after a pause/resume cycle that would
change the slot.

Add SocketKeepalive.start with parameter to enable dynamic
keepalive mode based on the existence of TCP connections.
This supports IPSec mode to notify KeepaliveTracker to disable
keepalive when keepalive is unnecessary to improve battery life.
Keepalive is controlled by periodically TCP socket status check
for both enable and disable. This is a transition commit and
is expected to be updated based on the socket creation or
destroy.

To prevent packets going through an underlying network when the
