Podman nukes bash prompt escape sequences

[Emilien Macchi]

When deploying an Undercloud with podman, the prompt doesn't return to line when pressing enter (carriage return escape sequence) and probably some other things don't work.

It's podman eating them when executed to deploy the undercloud, maybe when it copies things inside the container to outside when we attach.

Reproduced the bug:

$ echo $PS1
[\u@\h \W]\$

After a reset:

$ echo $PS1
[\u@\h \W]\$
