RESTBase: Increase log sampling rates
We started sampling normal & slow request logs recently, which has proven very
useful for tracking down large request surges. With the current settings, we
are logging about 12-15 requests *per hour*, which is at the lower end of what
is useful.
This patch increases the sampling rate by a factor of five (and 10 for slow
requests). This should result in roughly one log message per minute.
