cli: reimplement CLI completer using chzyer/readline (apache#38)

This moves the prompt implementation back to chzyer/readline with the following changes:
- Use a `tab-tab` and `enter` based approach similar to zsh
- Use readline based selector that removes option values in parenthesis
- Removes old go-prompt implementation and manual history utils
- Heuristics based API arg completion when there is no obvious API by arg name
- Better autocompletion for API args and its response key filter args
