(#17) Add auto-config examples

With this commit, the Manage view demo page will auto-load example
configs into the MTD editor. It has example names that will give the
user an idea of what a good config per key looks like.

Future work:

Allow for a user to insert more than 1 role/cluster/etc into a given key
assuming that key already exists in the config. This will be really
useful when editing an existing config that already has the basic keys
goals, roles, and clusters.
