plugins

   Thanks everyone for the review comments. I think there are enough 
substantial suggestions that we should go ahead and pause this PR. I'll divide 
this effort into smaller pieces, each of which is more complete to address the 
issues raised in reviews. This is all good news: shows that there is demand for 
an improved storage plugin API and that the present work is too modest an 
improvement. Let me figure out an alternative approach.

> The "Easy" framework allows third-parties to add format plugins to Drill with 
> moderate effort. (The process could be easier, but "Easy" makes it as simple 
> as possible given the current structure.)
> At present, no such "starter" framework exists for storage plugins. Further, 
> multiple storage plugins have implemented filter push down, seemingly by 
> copying large blocks of code.
> This ticket offers a "base" framework for storage plugins and for filter 
> push-downs. The framework builds on the EVF, allowing plugins to also support 
> project push down.
> The framework has a "test mule" storage plugin to verify functionality, and 
> was used as the basis of an REST-like plugin.
