This simplifies usage of Kaniko in GitLab CI environments and
means that it's not longer necessary to manually cobble together
the config with the right values from the environment in
error-prone shell commands.
Prior to this change, Kaniko disabled logging for its ecr-login
dependency by redirecting the logger's output to ioutil.Discard.
However, since that used the logrus standard logger, this had the effect
of completely disabling (redirecting to Discard) _all_ logging done by
Kaniko.
This caused integratiion test failures, and left any user of Kaniko
without any logging.
This fix updates the dependency on ecr-login to include a fix for this
issue, and updates to the new API introduced in that fix.
Previously the ecr-login cred helper we compile into the executor/warmer
binaries would log a warning when they were asked for credentials for a
non-ECR image. This takes advantage of recent work in ecr-login to let
consumers like kaniko disable that logging.
