Chassishandler: Add chassis identify state support for chassis status command

Return the present chassis identify state in get chassis status command:
Off
Temporary on
Indefinite on
Reserved

Tested:
Set chassis identify in different states:
ipmitool raw 0 4 10 0
ipmitool raw 0 4 0 1
ipmitool raw 0 4 0 0

Then query the chassis status and check on the third byte
ipmitool raw 0 1
