[Jib CLI] critical error message erased if rich console

[chanseokoh]

A lot of people will hit registry auth issues. When passing --console=plain, we can see the error and know what went wrong.

$ jib jar --target=openjdk --console=plain ~/tmp/embedded_jetty_hello_world.jar
...
Container entrypoint set to [java, -cp, /app/explodedJar:/app/dependencies/*, org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader]
Container program arguments set to []
[ERROR] I/O error for image [registry-1.docker.io/library/openjdk]:
[ERROR]     java.net.SocketException
[ERROR]     Socket closed
com.google.cloud.tools.jib.api.RegistryUnauthorizedException: Unauthorized for registry-1.docker.io/library/openjdk

However, by default, it's getting erased by the dynamic progress update. Also the output becomes messy.

$ jib jar --target=openjdk ~/tmp/embedded_jetty_hello_world.jar

This is a critical issue, as it hides the essential information.
