Previously, `clientv3.Lease.KeepAlive` interface does not return error (see [#7488](https://github.com/coreos/etcd/issues/7488) and [#7732](https://github.com/coreos/etcd/pull/7732)).
Before
```go
// clientv3
type Lease interface {
KeepAlive(ctx context.Context, id LeaseID) (<-chan *LeaseKeepAliveResponse, error)
KeepAliveOnce(ctx context.Context, id LeaseID) (*LeaseKeepAliveResponse, error)
}
```
After
```go
// clientv3
type Lease interface {
KeepAlive(ctx context.Context, id LeaseID) LeaseKeepAliveChan
KeepAliveOnce(ctx context.Context, id LeaseID) LeaseKeepAliveResponse
}
// check error
for ka := range <-LeaseKeepAliveChan { ka.Err }
LeaseKeepAliveResponse.Err
```
