campaignd: Add log-related FIFO commands

Browse source 
This adds 'log <severity> <comma-domain-list>' to change the log level
for one or more log domains without restarting the server, 'log precise
on/off' for changing the timestamp precision setting, and 'timings
on/off' for changing the request servicing timing reports setting.
