On the latest master branch, etcdserver/etcdserverpb/etcdserver.pb.go
is changed when scripts/genproto.sh is executed. The content only has
changes for comment. Therefore it is not important but the change is
annoying when we update the proto file.
Using Go-style import paths in protos is not idiomatic. Normally, this
detail would be internal to etcd, but the path from which gogoproto
is imported affects downstream consumers (e.g. cockroachdb).
In cockroach, we want to avoid including `$GOPATH/src` in our protoc
include path for various reasons. This patch puts etcd on the same
convention, which allows this for cockroach.

This commit also regenerates all the protos, which seem to have
drifted a tiny bit.
