Provide more context to ECA action plugins
Problem/Motivation
For ECA action plugins that implement the \Drupal\eca\Plugin\Action\ActionInterface, ECA already provides the dispatching event for the action plugins to get access to.
Sometimes, an action plugin may have to know more about the ECA action context itself, and this should be provided likewise.
Proposed resolution
Introduce the EcaAction object as a new property to ECA action plugins.
