Description:
When stop slave is executed on a semisync slave, a semisync master waits until it hits a timeout. There should be a functionality on slave to kill the connection on the master. This avoids master unnecessary waiting for timeout, instead it can turn semisync status OFF.

How to repeat:
stop slave; // on slave
insert on master; //waits for timeout

Suggested fix:
slave should kill the connection on master when 'stop slave' is executed.
