ignored_columns as a callback or as a service

[FluffyDiscord]

I would LOVE to have option to set some kind of service which would receive the entity and return array of ignored columns. Right now we can set ignored columns globally or per entity class, but sometimes I want to ignore entity column under specific conditions. Right now I do not have the option to do so, except implementing my own auditing service, which feels like an overkill.

TLDR: Please add option to dynamically set ignored columns for certain entity (not class, but object)
