Rewrite dumper in Go

Differences:
- All APIs are fully qualified in both the options (`--must-exist=certificates.cert-manager.io`, `--ignore=deployment.apps`) and the output files (`objects-Certificate.cert-manager.io.json`).
  This makes it possible to distinguish between objects with the same kind but different groups. See #47.
- Resources without a list endpoint are ignored and do not cause and error or need to be explicitly ignored.
- Ignore and must-exist options are now command line flags instead of files in `/usr/local/share`.

Fixes #47 and #42.
