Logging: raise severity level for logged messages
Nginx is inconsistent in respect to severity level used for messages that
are logged for user/server errors resulting in 4xx/5xx response codes.
There are some places where INFO level is used which makes hard to debug
user problems because setting logging level of 'error_log' to 'info'
produces
too much of an output whereas with this patch setting level to 'warn' gives
more relevant messages.
