Adds --log-commits commandline option. (#323)

* Adds --log-commits commandline option.

Similar to histogram support, the commit logging feature must be
enabled with a configure option: --enable-commitlog. However, unlike
that feature, there was no way to turn off the logging with a
commandline option once the functionality was built in. This (git)
commit provides that abilty.

* Changes addressing review feedback.
