Make a log entry with format

val emit : ?service_name:string -> ?attrs: (string * [< `Bool of bool | `Int of int | `None | `String of string ]) list -> t list -> unit

Emit logs.

This instructs the collector to send the logs to some backend at a later date. NOTE be careful not to call this inside a Gc alarm, as it can cause deadlocks.
