Ruby

Adds support for creating state machines for attributes on any Ruby class

EntityRequest#initialize

We use EntityRequest object to collect parameters and variables
from the controller. Because options that are being passed to the entity
do appear in each entity object  in the chain, we need a way to pass data
that is present in the controller (see  #20045).
