Format discovey JSON file in multiline

[mgoerens]

This is mostly for convenience, as it is much easier to edit a multiline file (e.g. delete a whole section) than a single line file.

For instance currently a discovery file would look like that:

{"DiscoveredImages":[{"PodName":"synapse-operator-controller-manager-74568cc478-kmkql","ContainerName":"kube-rbac-proxy","Image":"gcr.io/kubebuilder/kube-rbac-proxy:v0.8.0"},{"PodName":"synapse-operator-controller-manager-74568cc478-kmkql","ContainerName":"manager","Image":"quay.io/opdev/synapse-operator:v0.6.1"}]}

I'd suggest to have it directly formatted like this:

{
    "DiscoveredImages": [
        {
            "PodName": "synapse-operator-controller-manager-74568cc478-kmkql",
            "ContainerName": "kube-rbac-proxy",
            "Image": "gcr.io/kubebuilder/kube-rbac-proxy:v0.8.0"
        },
        {
            "PodName": "synapse-operator-controller-manager-74568cc478-kmkql",
            "ContainerName": "manager",
            "Image": "quay.io/opdev/synapse-operator:v0.6.1"
        }
    ]
}

Of course you can use an online formatter, or use your favorite IDE to format the file, or even run jq inside of vim, but it's not super user-friendly / convenient.

I agree with this, post processing this file to make edits is a problem.

Addressed via #13. The default is now formatted/pretty-printed JSON. Use the --compact / -c flag to get the previous behavior.
