Merge branch 'jk/avoid-localhost'

Various tests exercising the transfer.credentialsInUrl configuration
are taught to avoid making requests which require resolving localhost
to reduce CI-flakiness.

* jk/avoid-localhost:
  t5516/t5601: be less strict about the number of credential warnings
  t5516: move plaintext-password tests from t5601 and t5516
