[FEATURE] SQL Editor code auto completion

[JoshOY]

Is your feature request related to a problem? Please describe.

For most IDEs, code completion is an essential feature that developers heavily relies on.

Currently we are using monaco editor as the code-editing component in data development page. It now have the ability to hint and auto-complete some common tokens or keywords. BUT we still need to implement intelligence hints on field tokens (like table names, columns, etc.)

Describe the solution you'd like

We have made a few research on existing implementations.

1. pgcli
2. https://github.com/ascoders/weekly/blob/v2/085.%E7%B2%BE%E8%AF%BB%E3%80%8A%E6%89%8B%E5%86%99%20SQL%20%E7%BC%96%E8%AF%91%E5%99%A8%20-%20%E6%99%BA%E8%83%BD%E6%8F%90%E7%A4%BA%E3%80%8B.md
