Margo Crawford 74f5ed6b17 This introduces an Impersonate-Uid header to server side code. ... UserInfo contains a uid field alongside groups, username and extra. This change makes it possible to pass a UID through as an impersonation header like you can with Impersonate-Group, Impersonate-User and Impersonate-Extra. This PR contains: * Changes to impersonation.go to parse the Impersonate-Uid header and authorize uid impersonation * Unit tests for allowed and disallowed impersonation cases * An integration test that creates a CertificateSigningRequest using impersonation, and ensures that the API server populates the correct impersonated spec.uid upon creation.		2021-07-06 10:13:16 -07:00
