move major tom to extension

[patrickelectric]

Current behaviour

Right now major tom is part of BlueOS, we should move it to its own extension.
Discussion: #2183

Expected or desired behaviour

With that major tom updates and release can be done outside BlueOS.

Prerequisites

• I have checked to make sure that a similar request has not already been filed or fixed.

[patrickelectric]

• Update kraken to install default extensions automatically
  • We should check connection speed before install (for all extensions)
  • We should check tethered connection before install (for all extensions)
  • We should alert user if connection speed is slow or (tethered need to investigate) and ask for confirmation before proceeding
• Major tom should provide an status endpoint that helps kraken to verify if its ok
• Kraken should rollback to major tom factory version if major tom fails to start
• Kraken should be able to change major tom factory version and set a new default

Note we could put the available network interfaces on major tom if we desire to check for tethered network prefix

[ES-Alexander]

• Presumably the default extensions should also come included with the pre-built RPi images?
• Also, I think it's important that Major Tom should provide an interface page showing what data is being collected (and potentially providing settings to disallow certain variables, or just a "turn off" button), an explanation of what we use that for, and some stats on how many status updates have been sent, as well as how much data that's been.
  • It shouldn't be hard for users to get access to that information, and I expect telemetry is more palatable if it's very clear exactly what is being collected and sent.
