name property of ClientProviderOptions should accept symbol values

[wayou]

Bug Report

Current behavior

According to the doc:

The name property serves as an injection token that can be used to inject an instance of a ClientProxy where needed. The value of the name property, as an injection token, can be an arbitrary string or JavaScript symbol, as described here.

we can use Symbol as injection token for the microservice.

Input Code

@Module({
  imports: [
    ClientsModule.register([
      {
        // 🚨 Type 'symbol' is not assignable to type 'string'.ts(2322)
        name: Symbol('my_microservice'),
      },
    ]),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

Expected behavior

the name should accept Symbol values.

Possible Solution

packages/microservices/module/interfaces/clients-module.interface.ts

export type ClientProviderOptions = ClientOptions & {
-  name: string;
+  name: string | symbol;
};
