Add official @nestjs/mail module

Feature Request

Nest.js should have a mail module that provides an integration for nodemailer/email-templates. There are already third-party solutions available, for example:

• https://github.com/nest-modules/mailer (depends on nodemailer)
• https://github.com/toondaey/nestjs-mailer (depends on email-templates)

However, I suggest to provide an official solution like other major web frameworks (Laravel, Ruby on Rails or Spring Boot), as most business cases require mail services (e.g. password reset, notifications).

Describe the solution you’d like

@Module({
  imports: [
    MailModule.forRootAsync({
      useFactory: () => ({
        transport: 'smtps://[e-mail]:[e-mail]',
        defaults: {
          from: 'Example <[e-mail]>',
        },
        template: {
          dir: __dirname + '/templates',
          ...
        },
      }),
    }),
  ],
})
export class AppModule {}

But why should Nest not provide a solution out-of-the-box?

Because it adds to the maintenance overhead with little advantage to the framework and it really isn’t necessary that the Nest team do it all.

I completely agree with @jmcdo29 and also have a https://github.com/nestjs/nest/issues/5148#issuecomment-664003442 as well. You can just create your own module with advantage of any customization you want, so you don’t face any restriction or limitation from the framework itself. For me I like creating my own wrapper module as much as I like without worry any compatibility as long as you follow the Nest Module document.
