eca_content: Provide plugins for entity validation
Problem/Motivation
Currently we are able to validate form input in the eca_form module, by reacting upon the "Validate form" event. However, in many cases, the validation itself belongs to the level of the entity, and not just the form.
Since entities can have a validation handler, it would be great being able to add validation there using ECA.
Steps to reproduce
Proposed resolution
Add events, conditions and action plugins for being able to perform entity validation on entity level.
Remaining tasks
User interface changes
API changes
Data model changes
