Choosing the Stop_timeout value for the Zone Boot Component

The stop method for the zone boot component spends 60% of the value for the Stop_timeout performing a complete "shutdown -y -g0 -i0" within the zone. If that failed, the next 20% of the value for the Stop_timeout will be spent halting the zone performing a "zoneadm —z zonename" halt and perform some additional cleanup steps in order to force the zone into the state installed. Therefore the Stop_timeout value for the zone boot component should be computed so that 60% is enough to successfully shutdown the zone.
