INT-3749: Get rid of IECA logic

Browse Source 
JIRA: https://jira.spring.io/browse/INT-3749

Since `IntegrationEvaluationContextAware` isn't so "context-free" resource like `BeanFactory`
 and `ApplicationContext`, but just a specific bean in the context, we can't follow with `BeanPostProcessor` logic - bad architecture by level of responsibility.
 Therefore we should follow with standard Dependency Injection mechanism to retrieve `evaluationContext` for the particular component.

 Since we can't rely on the `@Autowired` because SI can be used from the raw XML configuration,
 we use utility method instead. The pattern to get the proper `integrationEvaluationContext` is:
 ```
 @Override
 protected void onInit() throws Exception {
 		super.onInit();
 		this.evaluationContext = ExpressionUtils.createStandardEvaluationContext(getBeanFactory());
 }
 ```
