Don't output JSON with newlines.
Don't output JSON with newlines.

- All output from ia-mine should be JSONL. Some responses from the
  Metadata API contain unescaped newlines. This causes a lot of issues
  when using `jq` are when parsing JSON line-by-line. to address this,
  parse JSON response returned from server, and dump it back to JSON
  before printing to stdout.
