[Feature][Dashboard][Manager] Creating schema of StreamSource by Statement

[featzhang]

Description

At present, when creating a Stream field, it needs to be input one by one, which is relatively inefficient, especially when there are too many fields, the input will be very difficult.

In order to improve the efficiency of creating new Stream fields, the following three batch import methods are provided:

1. CSV: "Comma-Separated Values", is a file format for storing and exchanging data in a tabular structure, where each row represents a record and each column represents a field. The values in each row are separated by commas, and each row is separated by a new line.
2. Standard SQL: Specify the field name, field type and field remarks through DDL statements
3. Excel: import Excel template
4. JSON：Input a JSON statement and specify the information of the field through three keys: Name, Type, and Comment.
