1、基本的put/get/del

#普通的get与delete
res = etcd.put('bar')
value, kv_msg = etcd.get('bar')
print(value)
print(etcd.delete('bar'))
print(etcd.get('bar'))

print(etcd.put('demo/bar1', 'doot'))
print(etcd.put('demo/bar2', 'doot'))
list_of_kv = list(etcd.get_all())
for value, kv_msg in list_of_kv:
    print("key:{}, value:{}" .format(kv_msg.key, value))

3、获取/删除带有前缀的键
