1. Fixed Berksfile syntax
2. Changes to settings LWRP to allow value to be another nested hash (json)   e.g. if you want to update HTTP Proxy Host for nexus repository you need to set property 'remoteProxySettings' to value '{"httpProxySettings" => {"proxyHostname" => "proxy.com", "proxyPort" => 81 }}'. Lo
gic with JsonPath and gsub doesn't seem to handle cases like this.
