Incorrect unit for snmp based hardware disk and memory meters

[Saba]

The unit displayed in telemetry is B for harware.memory.* and hardware.disk.* meters. But it is in KB.
It needs to be fixed in in response of CLI queries and in http://docs.openstack.org/admin-guide-cloud/content/section_telemetry-snmp-meters.html

I have added a code fix at : https://review.openstack.org/207199

    Corrected unit of snmp based harware disk and memory meters

    The unit of following hardware disk and memory meters is KiloBytes rather than Bytes
    hardware.disk.size.total
    hardware.disk.size.used
    hardware.memory.total
    hardware.memory.used
    hardware.memory.buffer
    hardware.memory.cached
    hardware.memory.swap.total
    hardware.memory.swap.avail
