Adds support for multiple datasinks in one route

[Aegid1]

fixes #1

• Makes use of multicast() from apache camel to enable multiple sinks in one route

• Enables the possibility to use a transformer on every sink in one route with the usage of multicast() and pipeline()

• Changes the syntax of the "transformers" keyword in the routes.json from a one-dimensional array to a two-dimensional array -> This ensures that each sink can have its own transformer, whereby successive transformations are also possible

• an exemplary configuration of routes.json would be: "datasource": "MqttConsumerAGV", "transformers": [["jsonataBatteryStatus"], ["jsonataSpeed"], ["jsonataAbsolutePosition"]], "datasinks": ["sink://tendobot/BatteryStatus", "sink://tendobot/Speed", "sink://tendobot/AbsolutePosition"], "trigger": "event"

Sure! I updated the eclipse validation status.

I see that the CI is failing at the examples. It is possible that you changed something that would break backwards compatibility?

[Aegid1]

Ah sure! I forgot to adjust the routes.json in the databridge.examples. Thank you for the hint!

[FrankSchnicke]

Sorry for the delayed response, due to Hannover Fair we were quite busy. Thanks a lot for updating the PR!

To ensure I'm understanding it right, the transformer "jsonataBatteryStatus" would be mapped to "sink://tendobot/BatteryStatus", "jsonataSpeed" to "sink://tendobot/Speed" etc.?

[Aegid1]

Dont worry :). Exactly! I have just seen that a check was not successful. Do you know why that is?

I have added a PR #308 built upon this PR with an improved datasink mapping configuration to avoid breaking changes

Those changes are now part of #308. Since this PR is already merged I will close this one.
