This PR mainly did the following 3 things: - Refactor NewEtcdKV API - Add unittests for `kv/etcd/`, raise the coverage up to 94% - Correct some APIs from version to revision The old NewEtcdKV() API took `clientv3.Client` as one of the input, making everyone who using this API had to create a new `clientv3.Client`. So there're a lot of repeated codes everywhere. Meanwhile, someplace didn't even check whether the `clientv3.New()` returned error or not, and the old API also didn't check whether the clientv3.Client was Nil. This caused issue#6955. Ectd's version and revision have nothing alike, they represent different concepts, but our APIs kind of mixed them all up. So I correct those APIs' names. Resolves: #6955 Signed-off-by: yangxuan <xuan.yang@zilliz.com>
