Drop load_config, write_config, lock_config[_xx],
check_lock, check_protection, is_template and config_file
in favour of implementions in PVE::AbstractConfig.
Implement guest_type, __config_max_unused_disks,
config_file_lock and cfs_config_path from
PVE::AbstractConfig in PVE::QemuConfig.
qm list and qm status both show suspended VMs as 'running'
while the GUI's status summary shows them as 'paused'.
This patch makes 'qm status' always request the full status
and adds an optional '-full' parameter for 'qm list' to
use a full status query to include the 'paused' state. (This
is optional as it causes qmp requests to all running VMs.)
Since write_config was always called with skiplock=1 except
once, it makes sense to drop this parameter like in
PVE::LXC::write_config . If needed in the future, the
caller can use check_lock before write_config anyway.
The method update_config wrapped update_config_nolock
using lock_config, but to prevent update races the whole
"read config", "do something", "write config" flow was
always protected by lock_config anyway, and update_config
was never called.
Thus, we can safely drop update_config and rename
update_config_nolock to write_config like in PVE::LXC .
