[feature]: Add a CRUD API with Actix Web and SurrealDB

### 👀 Is there an existing feature request for this?

- [x] I have searched the existing issues

### 🔖 Enhancement description

- Providing a sample app support to the [samples-rust](https://github.com/keploy/samples-rust) repository.
- It will be a API service built with Actix Web and with a multi-model database like SurrealDB.
- Providing the instructions for generating test cases for it using Keploy !!

### 🎤 Why should this be worked on?

This sample app can act as a PoC for the rust users who wants to test their application having a multi-model database (_like SurrealDB_) with the help of Keploy . Also such a sample app with a such a combination is not present

### 💻 Repository

samples-rust

Start in the samples-rust repository and review the existing sample applications before choosing the entry point for an Actix Web API backed by SurrealDB. Add CRUD support and document how to generate Keploy test cases; the work is done when the sample runs and those instructions are complete.
