Introduces Impersonate-Uid to client-go.

Browse Source 
* Updates ImpersonationConfig in rest/config.go to include UID
  attribute, and pass it through when copying the config
* Updates ImpersonationConfig in transport/config.go to include UID
  attribute
* In transport/round_tripper.go, Set the "Impersonate-Uid" header in
  requests based on the UID value in the config
* Update auth_test.go integration test to specify a UID through the new
  rest.ImpersonationConfig field rather than manually setting the
  Impersonate-Uid header
