New vertical format for predict

[michaelmdresser]

What does this PR change?

Note verticality is a little excessive when object names wrap. See https://github.com/jedib0t/go-pretty/issues/261.

Does this PR rely on any other PRs?

• Stacked on https://github.com/kubecost/kubectl-cost/pull/143
• Relies on API updates from https://github.com/kubecost/kubecost-cost-model/pull/1243 for resource amounts/costs

How does this PR impact users? (This is the kind of thing that goes in release notes!)

Overhauled kubectl cost predict formatting to use less horizontal space while adding more data: resource amounts, resource prices, and % cost change.

How was this PR tested?

$ go run cmd/kubectl-cost/kubectl-cost.go predict -r michaelkc -f ./test/multi.yaml
