apb push reports success even when the docker push has failed.

[eriknelson]

This might be a dupe because I think I made this issue previously but...

The docker client's push does not throw an Exception on a failed push. I am not sure if there is a better way to detect an error case, but you can open a pipe and read docker's output, parsing for an error. This is not ideal at all, so we should:

1. Investigate if there is a more reliable way of detecting a failed push aside from parsing its output.
2. We need to call out an error and halt if one has occurred.

This is the specific call in question: https://github.com/ansibleplaybookbundle/ansible-playbook-bundle/blob/master/src/apb/engine.py#L968

@jonnyfiveiq @tcunning closed #236 in favor of opening an issue specifically tracking this.

@eriknelson When I tried looking at the docker logs I see the following error message

@mkanoor Do you mind printing the version of the APB tool you are using? Also, it appears you are logged in as "system:anonymous", can you ensure that oc whoami -t returns a token and that the logged in user has access to the images?

To test this you can do: oc get images. If that succeeds then I wouldn't expect to see this error.
