cgroup: cpu quota: fix resetting period length for v1
The CFS period µs value for cgroup v1 needs to be >= 1 µs and <= 1 s,
so resetting it to -1 (like we cab do for the quota) cannot work.
So, when the period is passed as undefined it should be set to 100ms,
i.e., the actual default value:
> - cpu.cfs_quota_us: the total available run-time within a period (in microseconds)
> - cpu.cfs_period_us: the length of a period (in microseconds)
> - cpu.stat: exports throttling statistics [explained further below]
>
> The default values are:
> cpu.cfs_period_us=100ms
> cpu.cfs_quota=-1

commit c86cfb8bbd9b505d06b580582297fa670561437b dropped allow-hotplug
from the primary interfaces file completely on write, but that breaks
setups that come from plain Debian.
Instead, as stop-gap measurement, transform "allow-hotplug" to auto
in the PVE controlled config.
That avoids conflict and improves installing PVE on top of plain
Debian, as the interface still comes up after the first reboot.
But it is not ideal auto is not the same as hotplug, so we need to
also track that difference in the future, but that needs some
adaptions in the API too (change autostart from boolean to
string+enum or so=

net: add get_local_ip helper
Sometimes we need to have a fallback for gai (get_ip_from_hostname)
but cannot yet rely on configured networks (get_reachable_networks)
from kernel POV (those may not have been configured yet, e.g., on
boot), so the ones configured in /etc/network/interfaces would be
nice too then, as they're the ones that will get configured soon
anyway on boot.
Add a new helper that takes in all those sources and allows to return
a single (first found) or all of those addresses.
Still prioritize the address we get from getaddrinfo, as there the
admin has control through /etc/hosts, DNS and gai.conf and treat the
remaining ones as fallback.

IO::Socket::IP->new (or rather by Socket::GetAddrInfo, which at least
on my system always returns the v4 wildcard-address first).
the code now binds to:
* the provided $host if not undef
* '::' if $host is not set
* '0.0.0.0' if $host is not set and binding on '::' yields undef,

that IPv6 is disabled

schema: check format: parse list formats as arrays
Previously, the returned value would be only the last element or undef in case
of an empty list. There's only a handful of callers of check_format() that look
at the return value and AFAICT none of the exisitng ones is for a -list format.
But best to avoid any future surprises.
It has not shown any real value in the last decade+ it was enabled,
and it can actually add quite some performance overhead. E.g., if an
API endpoint returns a few 100k of relatively simple entries we can
easily require several seconds, even tens of seconds, to run the
return validation - making it easier to run into timeouts along the
transmit path to the client.
The CLI handler has it still enabled, normally there's no timeout
there as no HTTP transmit path is involved, and d.csapak had a slight
preference for that in an off-list discussion.
The actual implementations in PMG or PVE could enable it too if
running under debug mode.
