allowing for env override for "htts_only"

[jmervine]

For non-prod environments, it would be helpful to override this value via the environment. Especially in dogwood, where a custom domain is required for https.

@hone Should I closet this, or do you think it's worth including. It's been so long I've lost context. Also I don't believe the failure is related to my PR

  1) Simple routes should support custom routes
     Failure/Error: expect(response.code).to eq("200")
     NoMethodError:
       undefined method `code' for nil:NilClass
     # ./spec/simple_spec.rb:70:in `block (4 levels) in <top (required)>'
     # ./spec/support/app_runner.rb:51:in `block in run'

Willing to look deeper at some point though.

Hi

This buildpack is now deprecated and we are recommending people move the more actively maintained heroku-buildpack-nginx. For migration advice see here.

As such, I'm closing this PR out since we won't be making further changes to this buildpack.
