Handle multi-endpoints Kafka connect configurations

[damienfayet]

When adding kafka connect workers, we can only specify one url.

Most of the time we need it to be able to handle at least 2 Urls in order to handle multi-node connect workers. (when the first one is not available anymore, request have to sent tto the next one in the list.

Change that :

connects:
      - name: connectWorkerName
        url: "https://myUrl1:8083"
        username: user
        password: pass

to

connects:
      - name: connectWorkerName
        url: "https://myUrl1:8083","https://myUrl2:8083"
        username: user
        password: pass
