Description of problem:
Currently, during the undercloud/overcloud installation we only support pulling images from registries that not require authentication(registry.access.redhat.com being the default). Since registry.access.redhat.com is going to be replaced with registry.redhat.io which requires authentication we should provide a way for the user to input registry authentication credentials.
A potential workaround for now is to run docker login manually on both the undercloud and inside the mistral_executor container.
