Add a --reboot-nodes flag to the CLI (Allow daemonisation)

[thclark]

Feature request

Use Case

When you exit the gateway at an arbitrary time (eg the code crashes or container reboots), the nodes can be left in an unknown state, and require reboot to reset to a useable condition.

Current state

This prevents us from daemonising the installation of the gateway, requiring that we have to manually start each session via balena.

Proposed Solution

If the CLI had a --reboot-nodes flag, which executed a reboot of any connected nodes on start, this would allow us to address
the issue.

Hardware Aspects

I asked @tommasopolonelli "do we now/still have a method (a sequence of commands that we can send) to force a node to reset from remote commands?" Tommaso's response from teams:

"For sure would be an useful command, that unfortunately is not available at the moment"

So this would have to involve some development on the hardware side before we could implement from here. Note also The sequence would need to work for whatever state the node is in..
