Change template.config to template.config.default

[noelmcloughlin]

Instead of

  config: '/etc/template'

Can we instead have:

  config: 
    default: '/etc/template'

I want formulas to support multiple providers/implementations of a technology.
Basically I want {{ template.config[provider] }} to evaluate to correct config file name.

Thinking about it, this is more useful because it is clearer and scales better.

  config: 
    name:
      default: /etc/template/default.conf
      custom: /etc/template/custom.conf
    source:
      default: salt://template/jinja/default.jinja
      custom: salt://template/jinja/custom.jinja
    servicename:
       default_client: defaultClientDaemon
       default_server: defaultServerDaemon
       custom_client_a: customDaemonA
       custom_server_b: customServerA

I added service because the configuration files are typically used by services.
