Michael Solomon e3dcd315c7 Remove the need for cast (#40988) ...

With the current order, I have to cast to unknown and then to `Promise<any>`
```
  public set<T>(key: string, value: T, options: CacheManager.CachingConfig): Promise<any> {
    return (this.client.set(key, value, options) as unknown) as Promise<any>;
  }
```

With the new order I can just do:
```
  public set<T>(key: string, value: T, options: CacheManager.CachingConfig) { // returns type is Promise<any>
    return (this.client.set(key, value, options);
  }
```

and
```
  public set<T>(key: string, value: T, options: CacheManager.CachingConfig) { // returns type is void
    return (this.client.set(key, value, options, ()=> {});
  }
```
