[Enhancement] The log adds a data flow patrol function

[gaoxh]

The specific idea of ​​log data stream cruising is as follows:
Users can customize query nodes, and each query node must define a specific query content to form a basic data stream retrieval unit; on this basis, multiple data stream nodes can be defined, and the serial and branch of the data stream can be defined according to the inclusion relationship of the log retrieval content (similar to cat xx.log | grep aa | grep bb |grep cc), the order of the business process and the branch, so as to form a complete definition of the log retrieval data stream. The above content needs to be completed in a visual way through the UI and persisted to the database.
Triggering method: The retrieval startup method hopes to support two methods: automatic data cruising and manual cruising;
Main application scenarios: For complex business scenarios, long business processes, or complex business branches, querying log information becomes long and difficult to remember the context. With the data stream cruising function, frequently checked business problems can be defined as data streams, which greatly facilitates data retrieval and problem troubleshooting.

It is a good idea, and we will discuss it internally.
