Dominik Csapak 9e45e03aef tools/daemon: fix reload with open connections
instead of await'ing the result of 'create_service' directly,
poll it together with the shutdown_future

if we reached that, fork_restart the new daemon, and await
the open future from 'create_service'

this way the old process still handles open connections until they finish,
while we already start a new process that handles new incoming connections

Wolfgang Bumiller dc2ef2b54f tools::daemon: fetch exe name in the beginning
We get the path to our executable via a readlink() on

package reloads.

Wolfgang Bumiller 5e5eed5c3b use double-fork for reload
To ensure the new process' parent is pid 1, so systemd won't
complain about supervising a process it does not own.

Fixes the following log spam on reloads:
Apr 25 10:50:54 deb-dev systemd[1]: proxmox-backup.service: Supervising process 1625 which is not our child. We'll most likely not notice when it exits.

Wolfgang Bumiller 620dccf1a1 tools/daemon: dup the TcpListener file descriptor
Now that we let hyper shutdown gracefully we need an owned
version of the listening socket to prevent it from closing
before running the reload preparations.

Wolfgang Bumiller e4311382d9 tools: daemon: rename some structs
Reloadable resources are now 'Reloadable' instead of
'ReexecContinue'.

The struct handling the reload is a 'Reloader', not a
'ReexecStore'.

Wolfgang Bumiller 4422ba2c7f tools: daemon: add a default signalfd helper
Proxy and daemon for now just want to handle reload via
`SIGHUP`, so provide a helper creating the signalfd stream
doing that - this is simply a filtered stream which passes
the remaining signals through, so it can be used exactly
like the signalfd stream could before to add more signals.
