Pool improvement

New Options

OptionDescriptionTypeDefault
`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.
