Add new "-q" logging option (quiet mode) while in initialize mode
(-i), producing only one progress message per 5 seconds along with elapsed time and estimated remaining time. Also add elapsed time and estimated remaining time to the default logging(prints one message each 100000 rows). Patch contributed by Tomas Vondra, reviewed by Jeevan Chalke and Tatsuo Ishii.
