I hope to add a configuration that can configure requests initiated in the project, and the request headers will carry certain parameters.

### Describe the feature

Authentication is to obtain the current user's information through a parameter of the request header, and then perform authentication. Usually, some common parameters are also placed in the request header, so I hope to add a configuration somewhere in the project. For example, the URL of the request can be configured with the specified parameters or the request header with the specified parameters.

### Environment

Postcat version：V0.5.1
OS：Windows 11
