Use timeout futures for sections that might hang in certain error
conditions. This is mostly intended to be used as a safeguard, not a
first line of defense - i.e. best-effort avoidance of total hangs.
Not every future used for the HttpClient/H2Client is changed, only those
where a quick response is to be expected. For example, the response
reading futures are left alone, so data transfer is never capped with
timeout, only the initial server connect.
It is also used for upgrading to H2 connections, as that can take a long
time on overloaded servers.

if no groups were found, the task log was very confusing as it
contained no real information why nothing was synced, e.g.:
Starting datastore sync job 'remote:datastore:local-datastore:s-79412799-e6ee'
Sync datastore 'local-datastore' from 'remote/datastore'
sync job 'remote:datastore:local-datastore:s-79412799-e6ee' end
TASK OK
this patch simply logs how many groups were found and are about to be synced:
Starting datastore sync job 'remote:datastore:local-datastore:s-79412799-e6ee'
Sync datastore 'local-datastore' from 'remote/datastore'
found 0 groups to sync
sync job 'remote:datastore:local-datastore:s-79412799-e6ee' end
TASK OK

Fixes a bug in which the userid of the ticket cache is updated,
when a user connects, but the ticket itself is not.
This means a newly connected user has a previously connected
user's ticket and thus, cannot do anything, as the client will
attempt to use the invalid ticket.
e.g. if john@pbs connected to the server first, followed by
mike@pbs, the following would be stored in the ticket cache.
{
"localhost": {
"mike@pbs": {
"ticket": "PBS:john@pbs:AAAA",
"timestamp": 1601039326,
"token": "BBBB"
}
}

In theory, one can do std::mem::forget, and ignore the drop handler. With
the lifetime hack, this could result in a crash.
So we simply require 'static lifetime now (futures also needs that).
* add square brackets to ipv6 adresses in BackupRepository if they not
already have some (we save them without in the remote config)
* in get_pull_parameters, we now create a BackupRepository first and use
those values (which does the [] mapping), this also has the advantage
that we have one place less were we hardcode 8007 as port
* in the ui, add square brackets for ipv6 adresses for remotes

as well as remotes, so that user that are behind a

future that renews the ticket every 15 minutes
we still use the BroadcastFuture for the first ticket and only
if that is finished we start the scheduled future
we have to store an abort handle for the renewal future and abort it when
the http client is dropped, so we do not request new tickets forever

- remove chrono dependency
- 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
since converting from i64 epoch timestamp to DateTime is not always
possible. previously, passing invalid backup-time from client to server
(or vice-versa) panicked the corresponding tokio task. now we get proper
error messages including the invalid timestamp.

An flock on the snapshot dir itself is used in addition to the group dir
lock. The lock is used to avoid races with forget and prune, while
having more granularity than the group lock (i.e. the group lock is
necessary to prevent more than one backup per group, but the snapshot
lock still allows backups unrelated to the currently running to be
forgotten/pruned).
