**Describe the bug** kvstore/cache_kv.go中很多方法没有使用defer的方式来释放锁，可能会有死锁的风险 **To Reproduce** 如下代码可能 在获取锁之后若有执行异常则会崩掉，则全局锁则无法释放，造成死锁。  https://github.com/apache/servicecomb-service-center/blob/ce7afe04f5bcad594bede6204a37443bfa9c0a00/datasource/etcd/state/kvstore/cache_kv.go#L45C6-L45C6 https://github.com/apache/servicecomb-service-center/blob/ce7afe04f5bcad594bede6204a37443bfa9c0a00/datasource/etcd/state/kvstore/cache_kv.go#L55 https://github.com/apache/servicecomb-service-center/blob/ce7afe04f5bcad594bede6204a37443bfa9c0a00/datasource/etcd/state/kvstore/cache_kv.go#L62 https://github.com/apache/servicecomb-service-center/blob/ce7afe04f5bcad594bede6204a37443bfa9c0a00/datasource/etcd/state/kvstore/cache_kv.go#L69 https://github.com/apache/servicecomb-service-center/blob/ce7afe04f5bcad594bede6204a37443bfa9c0a00/datasource/etcd/state/kvstore/cache_kv.go#L76 https://github.com/apache/servicecomb-service-center/blob/ce7afe04f5bcad594bede6204a37443bfa9c0a00/datasource/etcd/state/kvstore/cache_kv.go#L82 https://github.com/apache/servicecomb-service-center/blob/ce7afe04f5bcad594bede6204a37443bfa9c0a00/datasource/etcd/state/kvstore/cache_kv.go#L95 **Expected behavior** 此处预期获取锁之后的执行逻辑无异常，及时把锁释放掉。 为了增强可靠性，可以通过defer的方式来释放锁。 **Platform And Runtime (please complete the following information):** Platform - OS: [e.g. iOS] - Browser [e.g. chrome, safari] - Version [e.g. 22] Runtime - Version [e.g. Go 1.11] **Additional context** Add any other context about the problem here. -- This is an automated message from the Apache Git Service.
