Ensure memory metrics are converted to kilobytes in pcp-free
Ensure memory metrics are converted to kilobytes in pcp-free

Implements Franks review point that pcp-free should make sure
that its working with kilobytes, instead of assuming that the
metric descriptor from the kernel PMDA will never change.  A
no-op for the present, but good future-proofing nonetheless.
