Output json

[chrisfsmith]

Implementing json output for issue #1.

Example:

./list_instances --json | jq '[.[] | select(.name | contains("foo")) | {name: .name, ip: .privateIp}]'

Output:

[
  {
    "name": "foo-eu01d_euwest1",
    "ip": "100.100.100.1"
  },
  {
    "name": "foo-eu01s_euwest1",
    "ip": "100.100.100.2"
  },
  {
    "name": "foo-na01d_useast1",
    "ip": "100.100.100.3"
  }
]
