RFR: Put the credentials lock in the remote repository

[Robin Westberg via github.com]

Hi all,

Please review the following change that puts the credentials lock (used when running integration tests) in the remote repository instead of a local file, to allow the tests to be launched from multiple hosts.

Best regards,
Robin
