Description of problem:
The response headers returned by OCP 4.4 are lower cased. We asked a question regarding this in https://projects.engineering.redhat.com/browse/LPINTEROP-812 EAP: OPENSHIFT 4.4 feature_freeze Testing but didn't get any response. Is this change documented somewhere (e.g. will be part of OCP 4.4 release notes)?

Version-Release number of selected component (if applicable):
