Container::exec weird behavior
I'm trying to run bash -c 'curl https://google.com' in a container and this is the output that I'm receiving below.
In the example I only modified the command being run to this:
let options = ExecContainerOptions::builder() ‣options: ExecContainerOptions ‣ExecContainerOptionsBuilder
.cmd(vec!["bash", "-c", "curl http://google.com"]) ‣&mut ExecContainerOptionsBuilder
.env(vec!["VAR=value"]) ‣&mut ExecContainerOptionsBuilder
.attach_stdout(true)
.attach_stderr(true)
.build();

I also had a thought that perhaps my PR #251 could be the cause so I went ahead and tested it with a commit before it was merged and it shows the same output.
From further investigation it looks like no output is correct.
Here is a yum -y update as an example:
