What Is the Current Behavior?

If the 'quoting' feature is enabled, then all pages, where quoting components are rendered (/account, /account/quotes), are not stable. This problem is caused by the automatic refresh of quoting entities with the use of the 'timer' operator in the quotingEntities$ observable pipe.

Issue Number: Closes #1264

What Is the New Behavior?

The quotingEntities$ function has a new automaticRefresh option. When the option is enabled, the timer operator will be executed right after the app is stable.

Does this PR Introduce a Breaking Change?

[ ] Yes
[ x ] No

Other Information

If the automaticRefresh option is enabled, it is necessary to subscribe to the quotingEntities$ observable in the component and to manually trigger the change detection. The reason for that is, that the used ApplicationRef.isStable observable runs outside of the Angular zone. It will not trigger the change detection automatically and not update the template.(https://docs.angular.lat/api/core/ApplicationRef)

Example from documentation:

constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {
  appRef.isStable.pipe(
    first(stable => stable),
    switchMap(() => interval(1000))
  ).subscribe(counter => {
    this.value = counter;
    cd.detectChanges();
  });
}

Interfaces should only be used to accept data of REST calls. Anyway, I 'd prefer to remove it at all.
If use use an interface only at one place you can define it at this place, otherwise in the model.
