Bug#13699303 - THREAD POOL PLUGIN IGNORES TIMEOUT.

PROBLEM: 
mysql provides a feature where in a session which is 
idle for a period specified by the wait_timeout variable
(whose value is in seconds), the session is closed
This feature is not present when we use thread pool.
FIX:
This patch implements the interface functions which is 
required to implement the wait_timeout functionality
in the thread pool plugin.
