Add repeatable --debug (short -d) enabling API request logging

[sttts]

We had 3 cases (to my knowledge in Slack) internally recently where up didn't behave well and it was hard to debug the case. This output is inspired by kubectl --v=9, printing all http requests and a curl command for further trial and error.

Side-effect: this is better than API documentation that nobody reads.

In contrast to kubectl, we use -v for version. Hence, --debug, DEBUG or -d.

I have a couple of small questions/nits, but I think this looks really useful -- thank you!

[sttts]

Have seen that pattern in a number of places, e.g. git clean -f -f -f to really force it.

Double checked that go run ./cmd/up controlplane -a upbound list --debug=3 also works.
