Better support for all the possible locations of berkshelf's config.json

[filler]

Hello --

Both berkshelf v2 and v3 support a config.json at various paths during runtime. The berkshelf_path in knife-block should be amended to accommodate these paths. It currently assumes ~/.berkshelf/. This change is helpful for teams which have a chef-repo where they store knife.rb configs and want to also centrally-store config.json.

Hi,

I am no longer using Knife Block at work and I do not have time to maintain it in my spare time owing to my personal life.

If you wish to submit a patch, please do so and I will get around to merging it when I can.

Sorry for any inconvenience.

Matt

@filler are you still using knife-block? If so, could you assess the current state of this and share what should be changed to make it work now?
