since the last update to docker commons plugin (version 1.20), we are unable to use the withRegistry method properly.

steps to reproduce:

create a short script with:

docker.image(<some recent version of docker in docker image>).inside
{
   docker.withRegistry("some private registry url", "valid credentials to the private registry")
   {
       /// we never reach this part...
   }
}

the script above yields the error:

Error: cannot perform an interactive login from a non TTY device

downgrading docker commons plugin to version 1.19 solves the issue.

I believe the problem is caused due to the (possibly) wrong implementation of --password-stdin in this line.

if more information is needed, please let me know and I will happily provide it.
