This patch sets some limits on custom fields: - an entity can’t have more than 100 custom fields defined on it - a custom field can’t hold a value greater than 10,000,000 characters The current implementation of custom fields is relatively complex and does an upsert in SQL at some point, thus preventing to simply add an `ActiveRecord` validation on the custom field model without having to rewrite a part of the existing logic. That’s one of the reasons this patch is implementing validations in the `HasCustomField` module adding them to the model including the module.
