No Longer Send Docker Config for Red Hat Hosted Registries

[acornett21]

Is your feature request related to a problem? Please describe.

With the release of milestone 2, if a partner uses preflight and uploads a non-usable dockerconfig, this makes all of their images un pull-able from the registry for their customers.

Describe the solution you'd like.

When preflight detects that the registry is Red Hat Hosted, no longer send the credentials that preflight used to pull the image, since proper credentials are already in Pyxis. We can check the below to make this determination

certProject.container.hosted_registry==true

Describe alternatives you've considered.
