yaml.load(s, Loader=...) requires Loader= argument always #561

Maybe it would make sense to keep the warning for another while.
Note that yaml.add_constructor (and other methods) will add given constructors to Loader, FullLoader and UnsafeLoader, so people will be wondering why none of their custom constructors have an effect.
It should be recommended to only use add_constructor for a specific loader, and ideally to their own loader inheriting from one of the existing loaders.
While (hopefully) most users by now are using a specific loader for loading, there is still code out there that just disables the warning, and will stop working if they used custom constructors via yaml.add_constructor.
If something stops working and they enable warnings to investigate, they should be able to see a helpful message saying that the default loader has now been changed.

I'll add a warning if Full or Unsafe loaders had constructors added and load() is called without an explicit Loader=

This started as load() defaults to Loader=SafeLoader but we all decided it was better to require Loader=... arg for load().

Is there a test for the missing argument case?
