RFC: Allow filtering logEvent output

[dgomesbr]

Is your feature request related to a problem? Please describe.

It's not, it's an enhancement

Describe the solution you'd like

Considering that logEvent param exists over @PowertoolsLogging, we should provide an option include only/exclude fields from the event log record itself, as such:

• AllowedFields: Set<...> Only log items contained on the List/Set
• PreventLogFields: Set<...>: Only log items not matching the List/Set
  ....

Describe alternatives you've considered

There are no alternatives when using LogEvent

Additional context

Hey @dgomesbr It definitely sounds like an interesting idea.

Could you please shed some more inputs on your thoughts here ? Like What and how you think of it behaving on nested payload etc ?

[dgomesbr]

@pankajagrawal16 as an user concerned with data being logged, but also conscious about logging, I would like to either pass a Predicate<? super String> predicate where users could pass whatever predicate they want, and maybe apply at PowertoolsLogger.java implementation level.

Does that adds up?

[msailes]

I was thinking about this. I think nested payloads makes this harder.

Could the user pass an implementation class name, we'd instantiate it and use it to do the filtering.

[pankajagrawal16]

I have created a PR which will let clients override the default object mapper used for serializing the event. This will also let client decide and how and what they want to log the event. #287

@dgomesbr I believe we can close this issue based on this ability as well. Thoughts?
