This would prevent Unicorn from adding default middleware,
as if RACK_ENV were always none. (not development nor deployment)

This should also be applied to `rainbows' and `zbatery' as well.

One of the reasons to add this is to avoid conflicting
RAILS_ENV and RACK_ENV. It would be helpful in the case
where a Rails application and Rack application are composed
together, while we want Rails app runs under development
and Rack app runs under none (if we don't want those default
middleware), and we don't really want to make RAILS_ENV
set to development and RACK_ENV to none because it might be
confusing. Note that Rails would also look into RACK_ENV.

Another reason for this is that only `rackup' would be
inserting those default middleware. Both `thin' and `puma'
would not do this, nor does Rack::Handler.get.run which is
used in Sinatra.

So using this option would make it work differently from
`rackup' but somehow more similar to `thin' or `puma'.
