Pool improvement

New Options

Option	Description	Type	Default
Option	Description	Type	Default
idleTimeout	Indicate idle time after which a pool connection is released. Value must be lower than @@wait_timeout. In seconds (0 means never release)	integer	1800
minimumIdle	Permit to set a minimum number of connection in pool. Recommendation is to use fixed pool, so not setting this value.	integer	set to connectionLimit value

This permits to set a minimum pool size, meaning that after a period of inactivity, the pool will decrease the inner number of connection to a minimum number of connections (defined with minimumIdle). By default, connections not used after idleTimeout (default to 30 minutes) will be discarded, avoiding reaching server @@wait_timeout.

Pool handle connection creation automatically, with now some delayed after failing to establish a connection, to avoid using CPU unnecessary. Authentication error in pool have now a better handling.
