the main motivation is that id can be used in REST API routes. previously,
the id was a path and this had a "/" in it. This made /api/v1/backups/:backupId
not work.
unlike sendmail, recvmail is always optional. this is the case because
the cloudron may not receive emails at all, so app always has to be
prepared for it.

notifications are now system level instead of user level.
To clarify the use events/notifications/email:
* eventlog - everything that is happenning on server
* notifications - specific important events (alerts)
* email - these are really urgent things that require immediate attention. this is for
the case where an admin does not visit the dashboard often. can also be alerts like
bad backup config or reboot required which are not events per-se.
Notes on notifications
* oom - notification only
* appUpdated - notification only
* cert renewal failure - only raise when < 10 days to go. also send email thereafter (todo).
* Backup failure - only if last 5 backups failed (todo).
* Box update - notification only. we anyway send newsletter.
* box update available - we raise a notification. no email.
* app update available - we already have update indicator on dashboard. so, no notification or email.
Alerts:
* backup config
* disk space
* mail status
* reboot
* box updated
* ubuntu update required
initially, i tried to put this in the current value field but that
is TEXT and has a size limit of 64K. TEXT also stores things with
character encoding, so we have to stash it as base64
after some more thought:
* If app moves to another location, user has to remember to move all this config
* It's not really associated with an app. It's to do with the domain info
* We can put some hints in the UI if app is missing.
part of #703
the main reason this is under app and not domain is because it let's
the user know that an app has to be installed for the whole thing to work.

We removed httpPort with the assumption that docker allocated IPs
and kept them as long as the container is around. This turned out
to be not true because the IP changes on even container restart.
So we now allocate IPs statically. The iprange makes sure we don't
overlap with addons and other CI app or JupyterHub apps.
https://github.com/moby/moby/issues/6743https://github.com/moby/moby/pull/19001
we can just use container IP instead of all this httpPort exporting magic.
this is also required for exposing httpPaths feature (we have to otherwise
have multiple httpPorts).
