Update OCP branding

[Updated story request]

Decision is to always display Red Hat OpenShift logo for OCP instead of conditionally. And also update the OCP login, errors, providers templates. https://openshift.github.io/oauth-templates/

Related note in comments.

[Original request]

If the ACM or the ACS dynamic plugin is enabled and there is not a custom branding set, then the default "Red Hat Openshift" branding should be shown.

This was identified as an issue during the Hybrid Console Scrum on 11/15/20201
