onctl sizes lists what --type accepts for the current provider. It's a new optional SizeLister interface, like ImageLister. This PR covers boxes, Hetzner and OVH; AWS, GCP and Azure come next, since they need region handling and filtering.

$ onctl sizes -p hetzner          # live output, location fsn1
NAME      VCPU   MEMORY    DISK      ARCH   PRICE/HOUR   PRICE/MONTH
cax11     2      4 GiB     40 GiB    arm    0.0096 EUR   5.99 EUR
cx23      2      4 GiB     40 GiB    x86    0.0088 EUR   5.49 EUR

$ onctl sizes -p boxes
NAME      VCPU   MEMORY   DISK

Per provider

• boxes: GET /api/sizes; the service's default is marked.
• Hetzner: server types offered in the configured location, with that location's prices.
  • Deprecated types are left out, and so are types not available there.
  • Prices are shown in EUR. Server-type prices carry no currency (only /pricing does), and ls's cost column makes the same assumption.
• OVH: flavors available in the configured region. No prices, because the API publishes none.
• fc / ch: says to use --vcpu/--memory, since these providers have no fixed sizes.

Output

• Sorted smallest first; the configured default is marked *.
• Columns no size fills in are left out, e.g. prices for OVH and boxes.
• onctl create --type <TAB> completes from the same list.

Tests

• Hetzner against a fake API: location filter, deprecation, prices for the right location, sort order, default.
• OVH against its fake API: region and availability filtering.
• boxes /api/sizes.
• The table formatting.
• go test -race -shuffle=on ./... and golangci-lint are clean.
• Checked live against Hetzner and boxctl.io.
