Improve connection status information

[joshk]

Useful information to show on the Device page (and possible on the Devices page for filtering) include:

• latency
• connection speed (it would require a speed test)
• connection strength (wifi and cellular)

Some information from @jjcarstens for when I do get to this:

• https://hexdocs.pm/vintage_net/readme.html#global-properties
• The first in available_interfaces is the active. You can also look at connection status for each interface
• I believe why this has also sat is because vintage_net is not a dep of link. So this might also be another use case of an extension
• (regarding the interface name for a cell connection) It depends on the implementation. Most typically wwan0 or ppp0
