feat: add json output to config:export

Browse Source 
This change adds json output as both key/value as well as a list of objects. The former can be used in quick scripting environments, while the latter allows higher-level languages to have a bit more structure around how environment variables are declared. Specifically, systems such as kubernetes understand the latter method, while the former can be used within Nomad job files.
