ARCHITECTURE CHANGE
 GTM LB AND PERSISTENCE moved into tmm now. So now gtm can
get high performance. (GTM CMP now)
 This help reduce gtmd’s load and increase its stability.

TMSH
BIG3D
BIG3D
GTMD
GTMD
MCPD
MCPD
BIG-IP A
BIG-IP B
CHANGE ON SYNC LOGIC
 Not use timestamp of wideip.conf now
 Use commit-id timestamp
 Also can see commit-id timestamp in iqdump
 No more sync the whole wideip.conf file. Use mcp message instead now.
PROBER POOL
 Use prober pool override GTM election logic of big3d.
 Note will not override gtm election logic of gtmd. So you will still see
the same result on which gtmd will be responsible. Need be careful
when checking logging.
 Prober pool can be applied to DC, server (not vs)
 If customer upgrade to v11, and get strange behavior, first check big3d
version which is running.
 You can find them in iquery message,
 In ihealth check gtm_module.xml
