Remove unused fields from API Responses

[chavda-bhavik]

Is your feature request related to a problem? Please describe.
It seems obvious that the createdAt, updatedAt, and __v fields are not used anywhere on the front end. so we can remove them from API responses.

Describe the solution you'd like

1. Add an Exclude decorator to an entity, like,

import { Exclude } from 'class-transformer';
export class MyEntity {
  ...
  @Exclude()
  createdAt: Date;
  @Exclude()
  updatedAt: Date;
  @Exclude()
  __v?: number;
}

2. Add __v in the SchemaDocument,

interface IMyDocument extends MyEntity, Document {
  _id: never;
  __v: never;
}

4. In the controller apply the ClassSerializerInterceptor interceptor, like,

import { Body, ClassSerializerInterceptor, UseInterceptors } from '@nestjs/common';
...

@UseInterceptors(ClassSerializerInterceptor)
export class MyController {
  ...
}

5. Build dal lib by running pnpm build:dal.
6. Test respective API is sending the correct response.

Sure @tarunsamanta2k20 Here is the list of entities & controllers you would like to apply this facility,

1. ColumnEntity and ColumnController
2. MappingEntity and MappingController
3. ProjectEntity and ProjectController
4. TemplateEntity and TemplateController
5. UploadEntity and UploadController

Entites are inside the libs/dal/src/repositories folder and Controllers are inside the apps/api/src/app folder. And you can check this guide to setup Impler locally.
