(BUG) PRM cannot work with streaming content

[logicminds]

Describe the bug
AFAIK, PRM is only able to work with tools that execute a command and exit. With tools like the puppet debugger that keep the input open there needs to be a way to stream the output back to the console and continue to forward input. Docker does not appear to be the issue since it can run a puppet debugger container just fine.

To Reproduce
Steps to reproduce the behavior:

1. prm install --git-uri https://gitlab.com/nwops/prm-puppet-debugger.git
2. prm exec nwops/debugger

Expected behavior
The debugger console would prompt for input instead of just exit right away

What versions are you running?:

• prm 0.1.0 36276c0 2022/01/31
• popos 21.10 (linux)
• docker 20.10.12

Additional context

# dockerfile generated via prm
FROM puppet/puppet-agent:7.11.0
RUN /opt/puppetlabs/puppet/bin/gem install bundler --no-document
RUN /opt/puppetlabs/puppet/bin/gem install puppet-debugger -f --conservative --minimal-deps --no-document
COPY ./content/* /tmp/ 
VOLUME [ /code, /cache ]
WORKDIR /code
ENTRYPOINT [ "/opt/puppetlabs/puppet/bin/puppet"]
CMD ["debugger"]

If I take the dockerfile generate above and create the image manually, then invoke it from the CLi the debugger works as expected.
