Loading relationships from existing entity instance inside the same instance

Issue type:

[x] question [ ] bug report [ ] feature request [ ] documentation issue

Database system/driver:

[ ] cordova [ ] mongodb [ ] mssql [x] mysql / mariadb [ ] oracle [ ] postgres [ ] sqlite [ ] sqljs [ ] react-native

TypeORM version:

[x] latest [ ] @next [ ] 0.x.x (or put your version here)

Steps to reproduce or a small repository showing the problem: It is possible to load relationships using an existing entity instance?

For example, I have an User entity with OneToMany relationship with the Reservation entity. Then I have a user (user = User.find(1) ) and I want the reservations property inside the user instance object like so(with no eager loading, lazy loading or query builder):

let user = User.find(1);
// do some processing
return user; 
/* 
expect: {
id : 1,
email : 'some@email'
}
*/

// load reservations
user.load('reservations')

return user;
/* 
expect: {
id : 1,
email : 'some@email',
reservations: [{etc},{etc},{etc}]
}
*/

PS. I cannot use eager loading because I will get circular error. The only option I see is by using lazy loading and adding the reservations array in my user instance like so:

let user = User.find(1);
let reservations = await user.reservations // after setting lazy loading in my entity
user.reservations = reservations;
return user;

This is funny. A few moments ago I found myself needing this feature and after a quick google I found out that I was the person who posted this issue on Github. lol

Maybe it needs to be added on a priority list or something? @pleerock
