    @olegz - there are a bunch of trailing whitespace and whitespace on blank 
lines in the xml and properties files. checkstyle doesn't complain as it checks 
the java code only, but it did cause warnings when I applied the patch

> So, several clients have expressed interests in using WorkFlow orchestration 
> frameworks such as Camel, Spring Integration etc. to be able to encapsulate 
> yet modularize and externalize the complexity of some of the custom 
> processors as well as handle some of the use cases that fall outside of scope 
> of Data Flow paradigm (e.g., transactional context and XA between two+ 
> Processors). 
> There is already a ticket to provide Camel support - NIFI-924. However 
> realizing that both Camel and naturally Spring Integration is based on Spring 
> Application Context it appears that instead of having multiple extensions we 
> should have a more generic extension for a Processor that would delegate its 
> processing to a bean in provided Spring Application Context (AC). This way AC 
> becomes a black box and could contain anything (e.g., Camel, Spring 
> Integration or some custom user code).
