Authentication and convenience issues of v2.0

[HuangGuSheng]

Version: v2.0
Hello, I deployed kubeeye v2.0 in the 1host 2member cluster:

1. The 2.0 version web page has no authentication
2. It is mandatory to add at least one node authentication (such as ssh)
3. The above two points lead to insecurity. You can open the web page without authentication and easily obtain the ssh information of all nodes
4. Why is it mandatory to add node information? The network environment in a multi-cluster environment is usually isolated
5. Can nodes be added in batches?
