Tone down poor connection avoidance
Until we figure out a way to compare a poor mobile network
against and poor wifi network and then weighing in other factors,
tone down wifi avoidance aggressiveness

Improve network avoidance
Adds a back-off based technique where the amount of time we wait before
avoiding wi-fi is increased.
This will reduce power consumption on devices that are experiencing high
variance on wi-fi

Enhancements for avoiding poor connection on wifi
- Avoid flapping
- Increase thresholds and monitor rssi more closely to detect consistently weak signal

Improve Wi-Fi hand-off
When Wi-fi connects at L2 layer, the beacons reach and the device
can maintain a connection to the access point, but the application
connectivity can be flaky (due to bigger packet size exchange).
We now use Watchdog to monitor the quality of the last hop on
Wi-Fi using signal strength and ARP connectivity as indicators
to decide if the link is good enough to switch to Wi-Fi as the uplink.
ARP pings are useful for link validation but can still get through
when the application traffic fails to go through and thus not best indicator
real packet loss since they are tiny packets (28 bytes) and have
much low chance of packet corruption than the regular data
packets.
Signal strength and ARP used together ends up working well in tests.
The goal is to switch to Wi-Fi after validating ARP transfer
and RSSI and then switching out of Wi-Fi when we hit a low
signal strength threshold and waiting until the signal strength
improves and validating ARP transfer.

This allows a carrier app to authenticate before we notify the user.
For future, we will provide an API that allows app to disable

Fix watchdog to stop ping after wifi disconnects
- The pings are delayed async messages that were getting handled
after a disconnect as well
- Increase poll time to 200 ms, so we block on a receive for 1ms every 200ms for a
sent packet

Finalize wifi watchdog default settings
- Reduce DNS counts from 15 to 5. 15 was for debug.
- Keep success scenario as atleast 1 being successful
- Wait for a second to start checks (for some setups)
- Use one bar as a start for doing periodic DNS checks
- Do a DNS check every hour (instead of half hour)
