Avoid errors on booting application in a cluster

[stephanpelikan]

On booting an application using vanillabp-camunda8-adapter in a cluster having more than one node, an error occurs since all nodes try to deploy the BPMNs files bundled, concurrently.

Since this is a normal situation for clusters the error should be suppressed.

Thoughts: BPMN deployment should be serialized by Camunda 8, but the record loaded before starting deployment is old. So the booting application does not see whether the BPMN deployment was done by the own Zeebe-request or by any concurrent request of another cluster-node.
