This allows for slighly cleaner / more natural placeholders, as it
doesn't require the context (`.`) to be specified;
- `{{command}}` instead of `{{.Command}}` or `{{command .}}`
- `{{flagValue "my-flag"}}` instead of `{{.FlagValue "my-flag"}} or `{{flagValue . "my-flag"}}`

Define a local type for methods to expose to the template, instead of
passing the cobra.Cmd. This avoids templates depending on features
exposed by Cobra that are not part of the contract, and slightly
decouples the templat from the Cobra implementation.

- add basic unit-test for the template utilities
- make sure the template parsing tests test both the current
template produced by the utilities, as well as a fixture
- rewrite the printer test to use fixtures
- use blackbox testing ("hooks_test")
