Basic self-reporting, core part

[Hocuri]

Part of deltachat/deltachat-android#2909

For now, this is only sending a few basic metrics.

Also, it's sending to [email protected], but this account doesn't exist yet. I know nothing about Promotheus, so, I'll need some help with this from @link2xt or so - alternatively, I can create a very simple bot myself (that doesn't use Promotheus).

Discussed with @link2xt a few days ago about aiming for writing a bot that accepts metrics and makes them available to promotheus (or some other way of creating graphs) so that the only thing for any metrics source (e.g. cronjobs at chatmail servers) to send metrics to the bot. The bot effort is not specified yet, but it probably makes sense to write a simple jsonrpc-python metrics collection bot (because that can be modified by anyone, mostly) and start with the use cases of the self-reporting and chatmail-reporting.

Prometheus is irrelevant here, it expects to pull metrics every N seconds or so.

I suggest to setup an email account and have a Python script that processes reports directly from the directory full of reports collected by the bot or even from the Maildir full of messages if we don't encrypt them. https://popcon.debian.org/ does this thing, reports are sent to [email protected] by a cronjob and then some perl and python scripts generate graphs that are presented on the website.

i rebased, adapted (hopefully correctly :) to changed set_verified() api and fixed two warnings.

then tested the result with the android-pr - very nice!

is there sth. that prevents this and the android PR from being merged?

Btw, i forgot to report, i sent my statistics on 2024.05.14 02:10:26 UTC and Statistics bot replied to me with the "Thanks..." message only on 2024.05.24 14:40:15 UTC, i.e. after 10 days. It's just interesting what was happening all that time
