Currently, openapiv3 discovery uses requestURI to discover resources. However, that does not work when the rest endpoint contains prefixes (e.g. `http://localhost/test-endpoint/`). Because requestURI overwrites prefixes also in rest endpoint (e.g. `http://localhost/openapiv3/apis/apps/v1`). Since `absPath` keeps the prefixes in the rest endpoint, this PR changes to absPath instead requestURI. Kubernetes-commit: d94c733ee2bfaedd9a1c45d58fbd56c99403c94d
