  -----------
  feat: use java.util.logging (#722)

Use java.util.logging to print log messages.
logging can be configured in a regular JUL way, and via
`-DloggerLevel=OFF/DEBUG/TRACE`
`-DloggerFile=logs/pgjdbc_${app}.log`     `${..}` can be used to use property names in the file name, including
`System.properties`.`%u`, `%g`, etc patterns from
https://docs.oracle.com/javase/7/docs/api/java/util/logging/FileHandler.htmlcan be used as well.
