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

we have information here not available in the access log, especially
if the /api2/extjs formatter is used, which encapsulates errors in a
200 response.
So keep the auth log for now, but extend it use from create ticket
calls to all authentication failures for API calls, this ensures one
can also fail2ban tokens.
Do that logging in a central place, which makes it simple but means
that we do not have the user ID information available to include in
the log.

This is a preparatory step to replace the task control socket with it
and provide a "reopen log file" command for the rest server.
Kept it simple by disallowing to register new commands after the
socket gets spawned, this avoids the need for locking.
If we really need that we can always wrap it in a Arc<RWLock<..>> or
something like that, or even nicer, register at compile time.

writing to a file can explode quite easily.
time formatting to rfc3339 should be more robust, but it has a few
conditions where it could fail, so catch that too (and only really
do it if required).
The writes to stdout are left as is, it normally is redirected to
journal which is in memory, and thus breaks later than most stuff,
and at that point we probably do not care anymore anyway.
It could make sense to actually return a result here..

reuse the FileLogger module in append mode.
As it implements write, which is not thread safe (mutable self) and
we use it in a async context we need to serialize access using a
mutex.
Try to use the same format we do in pveproxy, namely the one which is
also used in apache or nginx by default.
Use the response extensions to pass up the userid, if we extract it
from a ticket.
The privileged and unprivileged dameons log both to the same file, to
have a unified view, and avoiding the need to handle more log files.
We avoid extra intra-process locking by reusing the fact that a write
smaller than PIPE_BUF (4k on linux) is atomic for files opened with
the 'O_APPEND' flag. For now the logged request path is not yet
guaranteed to be smaller than that, this will be improved in a future
patch.

Add a generous limit now and return the correct error (414 URI Too
Long). Otherwise we could to pretty larger GET requests, 64 KiB and
possible bigger (at 64 KiB my simple curl test failed due to
shell/curl limitations).
For now allow a 3072 characters as combined length of URI path and
query.
This is conform with the HTTP/1.1 RFCs (e.g., RFC 7231, 6.5.12 and
RFC 2616, 3.2.1) which do not specify any limits, upper or lower, but
require that all server accessible resources mus be reachable without
getting 414, which is normally fulfilled as we have various length
limits for stuff which could be in an URI, in place, e.g.:
* user id: max. 64 chars
* datastore: max. 32 chars
The only known problematic API endpoint is the catalog one, used in
the GUI's pxar file browser:
GET /api2/json/admin/datastore/<id>/catalog?..&filepath=<path>
The <path> is the encoded archive path, and can be arbitrary long.
But, this is a flawed design, as even without this new limit one can
easily generate archives which cannot be browsed anymore, as hyper
only accepts requests with max. 64 KiB in the URI.
So rather, we should move that to a GET-as-POST call, which has no
such limitations (and would not need to base32 encode the path).
Note: This change was inspired by adding a request access log, which
profits from such limits as we can then rely on certain atomicity
guarantees when writing requests to the log.

The 'Ok::<_, Self::Error>(res)' type annotation was from a time where
we could not use async, and had a combinator here which needed
explicity type information. We switched over to async in commit
df52ba5e45 and, as the type annotation
is already included in the Future type, we can safely drop it.

while we probably do not add much more to them, it still looks ugly.
If this was made so that adding a World readable API call is "hard"
and not done by accident, it rather should be done as a test on build
time. But, IMO, the API permission schema definitions are easy to
review, and not often changed/added - so any wrong World readable API
call will normally still caught.

- depend on proxmox 0.3.8
- remove epoch_now, epoch_now_u64 and epoch_now_f64
- remove tm_editor (moved to proxmox crate)
- use new helpers from proxmox 0.3.8
* epoch_i64 and epoch_f64
* parse_rfc3339
* epoch_to_rfc3339_utc
* strftime_local
- BackupDir changes:
* store epoch and rfc3339 string instead of DateTime
* backup_time_to_string now return a Result
* remove unnecessary TryFrom<(BackupGroup, i64)> for BackupDir
- DynamicIndexHeader: change ctime to i64
- FixedIndexHeader: change ctime to i64
Also swap the order of a couple of `.map_err().await` to
`.await.map_err()` since that's generally more efficient.
