Piotr Tabor 830618e44d ./integration: Fix flakes due to .setupLogging race.
The source of problem was the fact that multiple tests were creating
their clusters (and some of them were setting global grpclog).
If the test was running after some other test that created HttpServer
(so accessed grpclog), this was reported as race.

Tested with:
  go test ./clientv3/. -v "--run=(Example).*" --count=2
  go test ./clientv3/. -v "--run=(Test).*" --count=2
  go test ./integration/embed/. -v "--run=(Test).*" --count=2

pkg/ is a collection of utility packages used by etcd without being specific to etcd itself. A package belongs here only if it could possibly be moved out into its own repository in the future.
