NetworkMonitor suspects stall if we get high tcp fail rate in
10s. In a cell transition frequently environment, a certain
percentage packets lost or retransmission may stay for a longer
time interval. The shorter tcp polling interval may not able to
get confident enough result. The looser timer may also
increase validated result in the metrics which may not a good
signal. Thus, increase the polling interval to address it.

Current metrics contains only DNS signal. Given TCP info is
also considered to detection data stall, the related TCP
information should be included into metrics.

Allow NetworkStack to send SockDiag netlink request and parse
returned tcp info. Evaluate the internet health from the tcp
information.

From mainline perspective, we should use android flag api
instead of using Settings. Thus, move the definitions into
NetworkStack.
