Add stackCycle feature for decrease useless connections

[davidshimjs]

If you are using a connection pool and suddenly handle more traffic than usual, the size of the connection pool increases. And the increased connections will survive because of the wait_timeout setting. (It usually set as 10-30 seconds) Keeping unnecessary connections is not good for running multiple servers.

However, this problem can not be solved because the mysql module only supports round-robin styles. So I added a pool option called stackCycle.

config.mysqlConfig.options = {
host: '10.255.0.128',
user: 'linkredit_devs',
password: 'KBBSK0znnqMf7ZOv',
database: 'linkredit',
port: 3318,
connectTimeout: 1000
}
const pool = mysql.createPool(commonConfig.mysqlConfig.options);
is it correct to configure the connection poo？
