 Description: Log level for this package. If "ERROR" is used, only errors from this package will show up in the console. If "WARN" is used, warnings and errors from this package will show up in the console. If "LOG" is used, every log from this package will show up in the console.
 
 - `portRetries: number`

 Description: Number of times to try connecting MySQL to a randomly generated port before giving up. According to the [MySQL Documentation](https://dev.mysql.com/doc/refman/en/server-options.html#option_mysqld_port "MySQL Documentation") if port 0 is used as the MySQL server port, the default value (3306) will be used. To get around this, a random number between 1025 - 65535 (inclusive) is generated and used for the database's port. If MySQL cannot successfully listen on a randomly generated port after `portRetries` then the `createDB()` promise is rejected. A warning is created when MySQL tries connecting to a port that is already in use. This option only applies for the MySQL port if the MySQL port is not explicitly set or if it's set to 0. This option also only applies for the MySQL X port if the MySQL X port is not explicitly set or if it's set to 0.

 Default: 1,000
 
 Description: If `downloadBinaryOnce` is set to `true`, `lockRetries` is the number of times to check to see if the lock for the binary has been released (meaning it has been successfully downloaded and extracted). If the number of retries exceeds `lockRetries`, the `createDB()` promise gets rejected. This option is also used for the number of times to check to see if the lock for libaio has been released (only on Linux distros that use libaio1t64 instead of libaio1)

 Description: If `downloadBinaryOnce` is set to `true` and/or on Linux distros that use libaio1t64 instead of libaio1, `lockRetryWait` is the number of milliseconds to wait before checking if the lock has been released.

If set to `true`, this package will use the latest version of MySQL instead of the system-installed version. If `false`, the package will throw an error.

This option can be used for things like initialising tables without having to first connect to the database to do that. The queries in the string get executed after ```mysql-memory-server```'s queries run. Uses the ```--init-file``` MySQL server option under the hood.
