[Feature request] Auto create timeseries of schema template

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar.

### Motivation

when the schema template been designed first, it maybe not perfect,sometimes we need to add new measurement node after the schema template been created, but there's no way to modify and increase timeseries of schema template

### Solution

provide an api to add new timeseries of schema template dynamically

### Alternatives

_No response_

### Are you willing to submit a PR?

首先定位现有的 schema template 创建 API 以及 Apache IoTDB 中 measurement node 的表示方式。定义用于添加新 timeseries 的 API 应如何运行，然后添加测试覆盖，证明之前创建的 schema template 可以接受新的 measurement node。
