Daniel P. Berrangé 5288d9d085 qga: implement a 'guest-get-load' command
Provide a way to report the process load average, via a new
'guest-get-load' command.

This is only implemented for POSIX platforms providing 'getloadavg'.

Example illustrated with qmp-shell:

(QEMU) guest-get-load
{
    "return": {
        "load15m": 1.546875,
        "load1m": 1.669921875,
        "load5m": 1.9306640625
    }
}

Windows has no native equivalent API, but it would be possible to
simulate it as illustrated here (BSD-3-Clause):

This is left as an exercise for future contributors.
