Enable LoggingConfig configuration on Lambda Functions about serverless

[tomaszjezierski-olx]

Hey, this feature looks great and would allow us to reduce the cost. I have one question: shouldn't be there a possibility to set the LoggingConfig also on the provider level? Each Lambda probably is going to share the same configuration for logging, so it will reduce the boilerplate.

Looking at the documentation, it seems that defining LoggingConfig is a good idea.

What about the following settings?

functions:
  hello:
    ...
    loggingConfig:
      applicationLogLevel: <value>
      logFormat: <value>
      logGroup: <value>
      systemLogLevel: <value>

Can I please be assigned to this one?

Whilst we're waiting for feedback, anyone who needs this functionality now can look towards: https://www.npmjs.com/package/serverless-logging-config

Maybe the issue I opened over at #12284 should be folded into this one? It's asking for pretty much the same thing. When I wrote it, I honestly didn't even know it was a new feature. I just assumed everyone supported json through and through these days.

Thank you for your input. We've implemented the requested feature in V.4, available for both Provider and Function settings. For the correct YAML usage, check out the serverless.yml documentation, and for the function examples, simply scroll down. We're aware of an inconsistency with a titlecase YAML property. Rest assured, this will be corrected by Monday, as noted in this issue.

Looks like that was just a documentation typo and the YAML implementation correctly uses camelCase. This feature is ready to go.
