Can't use go-config beyond version 0.7.0

[etsauer]

Description of Issue

After go-config v0.7.0, our operator breaks on startup citing that there is no provider configured.

How to Reproduce

Update the following constraint in Gopkg.toml from 0.7.0 to any later release:

[[constraint]]
  name = "github.com/micro/go-config"
  version = "0.7.0"

Install dependencies and start operator:

dep ensure
operator-sdk up local

Expected result

Operator starts successfully

Actual Result

panic: There was a problem detecting which provider to configure. 
	Provider kind `` is invalid. 
{"provider":{"kind":""},"general":{"annotations":{"status":"","status-reason":"","expiry":"","format":""}}}

The version of go-config being used at this point is v1.1.0. Shouldn't we close this issue now? @etsauer

@AdlerFleurant yes we can close, but can you first add a reference to the PR that resolved it?
