Chef::Knife::SubcommandLoader::CustomManifestLoader#find_subcommands_via_manifest

If the user has created a ~/.chef/plugin_manifest.json file, we'll use
that instead of inspecting the on-system gems to find the plugins. The
file format is expected to look like:

  { "plugins": {
      "knife-ec2": {
        "paths": [
          "/home/alice/.rubymanagerthing/gems/knife-ec2-x.y.z/lib/chef/knife/ec2_server_create.rb",
          "/home/alice/.rubymanagerthing/gems/knife-ec2-x.y.z/lib/chef/knife/ec2_server_delete.rb"
        ]
      }
    }
  }

Extraneous content in this file is ignored. This is intentional so that we
can adapt the file format for potential behavior changes to knife in
the future.
