  • Adds forkJoin({ foo, bar }) such that it will return an Observable<{ foo, bar }> containing the values emitted from the sources held at the properties of the passed object.
  • DEPRECATED: forkJoin(a, b, c, d) should no longer be used, rather, just pass an array such as forkJoin([a, b, c, d]).
  • Reduces the size of the fork join code a bit
    Been wanting to do this one for a while. Going to try to get combineLatest also. (Inspired to get to it by @cartant ❤️)

This PR deprecates all `combineLatest` signatures except `combineLatest([a, b, c])`, in order to make `combineLatest` smaller in an upcoming version, and in order for `combineLatest` to ever accept a dictionary of observables (and emit a dictionary of values), these extra functionsignatures need to be deprecated ahead of time to signal their future removal.
