API Request: number of processors (including threads) #474

I saw that shard is able to compute the number of processors, optionally also including threads.

It would be great if this could be available via an API like Dagger.nprocs

We now have Dagger.all_processors() and Dagger.compatible_processors(scope::Dagger.AbstractScope) for getting the set of processors, and so we could implement a Dagger.num_processors() that does what you ask. I would avoid overloading nprocs, since Distributed exports that as well (and we use it in Dagger internally).
