[FEATURE REQUEST] Session Async Methods

[angelhdzmultimedia]

I suggest making the methods of the session object in the request async , mostly for session.destroy.

I've found myself doing this in NestJS:

return new Promise(resolve => session.destroy(() => resolve())

Would become:

@Get('logout')
public logout(): Promise<void> {
  return session.destroy() 
}

and:

@Get('logout')
public async logout(): Promise<void> {
  await session.destroy() // Promise<void>
  Logger.log('Destroying the session...')
  return
}

And making the callback optional.
