[pve-devel] [PATCH qemu-server docs manager] Implement support for fw_cfg

[Leo Nunner]

This patch introduces an interface for passing values to a guest via the
fw_cfg parameter. Settings are in the format

    opt/$key=$value

Where $key should start with a rfqdn (but doesn't need to). Both plain
strings and files (only from the snippets directory) can be passed through.
An example application for this parameter is for provisioning CoreOS
systems [1].

Files are currently passed through if the user specifies the value as
"storage:snippets/file", there is no implicit file flag.
