c68661e1a5 switch: guard the IMEI generation with a timeout
So that we can be reasonably sure that the script terminates and the
switch works again.

03c262a8c3 blue-merle: generate a temporary IMEI before the the SIM switch
After shutting down the modem and before replacing the SIM, we generate
a temporary random IMEI to prevent accidental disclosure of the new IMSI
under the old IMEI. It should not happen but we do not control the modem
as much as we'd like, e.g. fully power it down. So it may not be
necessary but we consider it defense in depth.

fe4021feb9 blue-merle: restore old scrpit for SSH use
We restore from fa11fc45ca.
We know that this worked well enough the last time as we run out of time
to test new things.
Ideally, though, we manage to consolidate the SSH use and the switch use
(and the Web use) to not have different implementations of the same
functionality so that testing gets much simpler.

0fbb00612c blue-merle: provide a somewhat interactive way to set a new IMEI via SSH
This can currently only provide a random IMEI only. But we could easily
recover the deleted script. But it'd be nicer to have a central
configuration for the mode.

We have separated it into stages so we don't need the monolith

0b4b04c48b switch: log in stage2
So that we can notice whether our script has successfully run.
You can read the log with something like
logread -l 10000 -e blue

ed6856c490 switch: split the switch action into separate stages
When toggling the switch, a lock is held for a relatively long time,
preventing another toggling of the switch to be noticed. With this
change, I hope we can first shutdown the modem, wait for a toggle, and
then continue.
We're losing the abort function but I currently don't know how we would
be able to keep that functionality given that the toggle is queued and
we don't get the notification.
