To provide example in not secure mode

I found it useful to have an example of insecure server-client example.

E.g., to check the running services (e.g., orchestration, serviceregistry, authentication)
```
import requests
r=requests.get('http://127.0.0.1:8443/serviceregistry/echo')
```
and in quickstart_setup.py, change the ServiceInterface to be:
```
ServiceInterface('HTTP', 'INSECURE', 'JSON'),
```
Inaddition, add 'NOT_SECURE' instead of 'CERTIFICATE'
```
hello_form = ServiceRegistrationForm.make(
Service(
'hello-arrowhead',
'hello',
ServiceInterface.from_str('HTTP-INSECURE-JSON'),
'NOT_SECURE',
),
systems['provider'][0],
)
````

从 quickstart_setup.py 开始，检查 ServiceInterface、ServiceRegistrationForm 和 Service 的定义，以了解请求的不安全值在哪里被处理。验证 HTTP-INSECURE-JSON 示例可以查询服务注册表，并且请求的 NOT_SECURE 注册值会被接受。Issue 中没有提到测试或其他文件。
