Try to solve TC 5.22 errors

[vga91]

Try to solve TC 5.22 errors:

• BindException: Address already in use
  Changed 1080 with PortFactory.findFreePort() in WatsonTest and LoadCsvTest to avoid the error.

• queryReadOnlyVectorsWithMapping FAILED, Caused by: java.net.SocketTimeoutException: Read timed out
  Tried several time but not replicated, it could be a sporadic flaky error

---

• mock server error:
  See here.
  Copied assertion to LoadS3Test, since otherwise there is the following error,
  as the org/mockserver/socket/PortFactory module is not included in extended-it, that is where the LoadS3Test is located
