Create CRUD for member without DB

[khattakdev]

This is how Discord object looks like

export class CreateDiscordDto{
  id: number
   username: string;
   bio: {
      description: string;
      twitter: string;
      linkedin: string;
      github: string;
   };
   updatedOn: Date;
   createdOn: Date;
}

I've added id temporary, to track down objects for the update, single search, and deletion. Once we have a database, we can remove it, if we don't need it but for now, it's something needed.

I've tested the API(s) as well, and they are working perfectly fine.

Get Single Record

Update Record

Insert Record

Delete Record

Get All Records
