Adds Camel Flowable component

[tijsrademakers]

Description

This adds a new Camel component to send and receive messages / events from Flowable (https://flowable.org and https://github.com/flowable/flowable-engine). Flowable is an open source BPM project that had a Camel integration since the beginning of the project 7 years back. This contributes the Flowable Camel component to the Camel project to make it easier for Camel users to make use of the Flowable integration.

this code needs more review and updates to a Camel v4 style.

Does flowable require spring or what is the requirement for using spring / camel-spring ?

[tijsrademakers]

Hi Claus, thanks for checking the PR. Flowable doesn't 100% require Spring but it's the easiest way to configure and use it. Let me know what should be changed for a Camel v4 style.

[davsclaus]

Well it needs to be decoupled from spring and be able to run independent and configured more standard Camel, like all other components.

Camel today runs in pure camel (and with jbang) and as well on Spring Boot or Quarkus. And components need to work all places.

[davsclaus]

And then the component need to be marked up with camel specific andantinos to make it document and tooling friendly - which also makes it useable with java fluent builder (endpoint-dsl).

Hi, the PR has been updated to fully remove the dependency to Spring.
