Context:
In order to test and validate the camunda events support (OPT-2955) for event based processes we need to extend the test data generator (qa/data-generation) in the following ways:
AT:
- at least two processes should get seeded with the same businessKeys so we can correlate them to an e2e process
- at least two processes should get seeded with the same values for a variables that can be used to correlate them (e.g. invoiceNumber of the invoice process)
