Problems on ZendQueue\Adapter\Db

[igormx]

I dunno if i have my fork updated but in ZendQueue\Adapter\Db i am seeing a couple of problems, for example its using Zend\Db\Select instead Zend\Db\Sql\Select and uses the constant Select::FOR_UPDATE that in Zend\Db\Sql\Select doesn't exist anymore.

Move the use sentence from Zend\Db\Select to Zend\Db\Sql\Select isn't a big deal, but i don't have any idea what to do about the constant Select::FOR_UPDATE that is used many times on ZendQueue\Adapter\Db.php.
