VOM: logging, populate and stats fixes
logging: allow a client to register a callback handler to recieve log messages that way the client can maintain a correctly sequenced log populate: fix the creation of interface and the setting of the handle stats: the reset promise idea is not defined behaviour. Use an eanble/disable command pair Change-Id: I347720bb65df2874c7619e722d593bc863ee2bf1 Signed-off-by: Neale Ranns <neale.ranns@cisco.com>
