Summary

At the moment the logging verbosity is not configurable for the "set service dhcp-server" node in the configuration.

I suggest we add a new node to the configuration allowing the user to set the log level to one of the pre defined values: FATAL, ERROR, WARN, INFO, DEBUG

Use case

As the configuration for logging is never set Kea (the underlying software which implements this node) defaults to the "INFO" logging level. This level causes every single DHCP packet to be logged to syslog. This quickly overwhelms the log on a moderately active system and means that either a large amount of logs needs to be stored or the log rotates very quickly meaning it can be hard to fault find.

Allowing the log level to be set gives control to the user to decide how much logging they want at what time.
