Ent: Feature Request: contextual logging

[ernado]

Sometimes it is useful to support logging with context.
E.g. I want to distinguish logs that belong to single request.

Could be achieved by allowing a logging function to receive a context:

func LogCtx(fn func(ctx context.Context, i ...interface{})) Option {
    return func(c *config) {
        c.logCtx = fn
    }
}

Or by something like func getLog(ctx context.Context) func(...Interface{}) function that will return logging function for provided context.

Btw, thank you for your great project.

Sounds good, feel free to send a PR updating the current logging function as suggested above.

The codegen doesn't emit logs today - what emits them is a dialect wrapper called dialect.DebugDriver.

It can be achieved today by providing your own wrapper. However, I agree that it's nice to have that, so a PR is welcome for something like DebugWithContext (like RequestWithContext).
Note that, if you're using ocsql or something similar, you won't see additional logs than what ocsql emits.

@ernado If you don't mind, I'm really interested implementing this feature. I actually need this to use ent with zerolog.

Hey @aca, feel free to submit PR, it would be great!

I'm currently actively prototyping new project with ent, so slightly out of capacity and can't do it myself.
