do here as well

Fix #2476: Fix auto-ballooning QMP command
Commit 0dd73a7fec (statd: refactor update_node_status) changed $target
in pvestatd's auto_balloning sub into a variable:
my $target = int($res->{$vmid});
but then uses it in a string as a parameter to the $log function:
$log->("BALLOON $vmid to $target (%d)\n", $target - $current);
This surprisingly causes the variable to be incorrectly converted into a
JSON string by perl's to_json (called in QMPClient after mon_cmd):
{"value":"1234"}
instead of
{"value":1234}
which causes QEMU to report the parameter as invalid:
"Invalid parameter type for 'value', expected: integer"
This behaviour is made even trickier, since $target internally is still
considered more of an 'int' (although that's a weak claim in perl
anyway), showing up without quotes in Dumper et. al. - but the perldoc
for to_json scheds some light:
simple scalars
Simple Perl scalars (any scalar that is not a reference) are the
most difficult objects to encode: this module will encode undefined
scalars as JSON "null" values, scalars that have last been used in a
string context before encoding as JSON strings, and anything else as
number value
So coerce to_json to treat $target as an integer by using it as one and
everything is fine again.

Add 'type' option to AgentFeatureSelector
This adds an extra field to the AgentFeatureSelector that reflects the
change in qemu-server.
Changes since previous version:
* Use map rather than if/else if/else for type display string.
* Use Proxmox.Utils.unknownText for unknown type (should not occur with
regular use).
* Keep existing fields as boxLabel rather than fieldLabel, as they
look crammed with fieldLabel.
* Use __default__ for default option, to save space and replicate
behaviour in other places.
* Store option in advancedItems as it is a special case.
Even though the map only contains one item, it will be easily added to
in the future. There is only one item as there is no need to have a
string for "virtio" as it is not displayed because of __default__.

fix #844: allow to pre-delay start-all-marked guests on boot
Add a simple ExecStartPre command which reads the local node config,
and if a delay is set the helper sleeps that long then exists.
The systemd-unit approach was chosen as this ensures that we really
only delay when doing the startall on node boot. The pve-guests
service does not allows manual stops, starts or restarts, it can only
be pulled in by the multi-user.target
Mark this command with "-" to tell systemd that errors of it should
not cause an abort, it's a best-effort approach.
The journal from a 2 second delay would look like:

Fix #352: Limit the length of backup logs for mails
When creating a backup the log part can make the mail too big to be
transferred. To ensure delivery, two measures are taken:
1. Always omit the status lines
2. Omit the whole log part if a mail becomes (too) big
Additionally, add a check for missing log files.

it seems that we have a reference leak or the like somewhere in the

Until we can track that down, or abandon perl for good, avoid to
frequent restarts by allowing statd to grow 15 MB of memory usage

status/graphite: refactor write_graphite to send all at once
Instead of doing multiple sends, for each status metric line one,
assemble it all in a string and send it out in a single go.
Per VM/CT/Node we had >10 lines to send, so this is quite the
reduction. But, also note that thanks to Nagler's delay algorithm
this may not had a big effect for TCP, as it buffered those small
writes anyhow.
For UDP it can reduce the packet count on the line dramatically,
though.

status/graphite: reduce default timeout to 1 second
This is for TCP only, and TCP needs roughly 1.5 time of the Round
Trip Time for connection setup, So, with 1 second timeout we're still
good for connections with 660 ms latency in-between.
The assumption is that most of the time the status server is
relatively near (same datacenter, or region), and connections to it
are datacenter grade, and not like a spotty GPRS modem.
So, reduce this timeout to ensure that we do not block to long.
If anybody needs higher timeouts they can just change the default
anyway.
