[feat] use bonafide Provider object as a singleton

There was common situations where two provider instances where running
in parallel. And was creating weird errors (like getting wrong api_uri)
because the bootstrap deferreds were global but the Provider objects
not.

I don't like much singletons, but I think now is simpler than before.
