Lays out a log event as a JSON string

Configuration parameters that may be used:
- compact: to serialize compact JSON structures. the serialization rather
produces a "prettyprint" JSON structure by default.
- messageAsObject: to serialize the message as an object structure. The
message gets serialized as a string by default.
- depth: the depth to with message parameters should be serialized. Only
useful when "messageAsObject" is set.
