The http-server has a 64KB payload limit for post requests, so note
that explicit even if it's a theoretical maximum as the reamainig
params also need some space in the request

'input-data' can be used to pass arbitrary data to a guest when running
an agent command with 'guest-exec'. Most guest-agent implementations
treat this as STDIN to the command given by "path"/"arg", but some go as
far as relying solely on this parameter, and even fail if "path" or
"arg" are set (e.g. Mikrotik Cloud Hosted Router) - thus "command" needs
to be made optional.
Via the API, an arbitrary string can be passed, on the command line ('qm
guest exec'), an additional '--pass-stdin' flag allows to forward STDIN
of the qm process to 'input-data', with a size limitation of 1 MiB to
not overwhelm QMP.
Without 'input-data' (API) or '--pass-stdin' (CLI) behaviour is unchanged.

QMP and monitor helpers are moved from QemuServer.pm.
By using only vm_running_locally instead of check_running, a cyclic
dependency to QemuConfig is avoided. This also means that the $nocheck
parameter serves no more purpose, and has thus been removed along with
vm_mon_cmd_nocheck.
Care has been taken to avoid errors resulting from this, and
occasionally a manual check for a VM's existance inserted on the
callsite.
Methods have been renamed to avoid redundant naming:
* vm_qmp_command -> qmp_cmd
* vm_mon_cmd -> mon_cmd
* vm_human_monitor_command -> hmp_cmd
mon_cmd is exported since it has many users. This patch also changes all
non-package users of vm_qmp_command to use the mon_cmd helper. Includes
mocking for tests.

SHA-512 crypted passwords are longer than 64 byte, and it also does
not make sense to limit passwords to such a short length. Increase
to 1024, that should be enough for a while, but still limits maximal
password payload to avoid DOS or the like.

this api call reads a file via the guest agent,
(in 1MB chunks) but is limited to 16MiB (for now)
if the file is bigger, the output gets truncated and a
'truncated' flag is set in the return object

this imitates the qemu-guest-agent interface
with an 'exec' api call which returns a pid
and an 'exec-status' api call which takes a pid
the command for the exec call is given as an 'alist'
which means that when using we have to give the 'command'
parameter multiple times e.g.
pvesh create <...>/exec --command ls --command '-lha' --command '/home/user'
so that we avoid having to deal with shell escaping etc.

with a 'register_command' sub, which generates an api call
we call it for each command in the list, and one time for
the old general {vmid}/agent endpoint (for compatibility)
permissions/methods are the same as previously, but can
be overriden
