This PR adds proxy and scheduler predicate related conformance annotations to the e2e test suite.

The PR fixes a portion of #53822. It focuses on adding conformance annotations as defined by the Kubernetes Conformance Workgroup for a subset of the pod based e2e conformance tests.
Special notes for your reviewer:
Please see https://docs.google.com/spreadsheets/d/1WWSOqFaG35VmmPOYbwetapj1VPOVMqjZfR9ih5To5gk/edit#gid=62929400
for the list of SIG Arch approved test names and descriptions that I am using.
