Implement configuration handling

This patch implements basic configuration handling that reads a
configuration file and stores the parsed data in the ExecCtx and RunCtx
structs.  It supports three configuration items:
- model (previously only --model)
- no_cache (previously only NITROCLI_NO_CACHE)
- verbosity (previously only --verbose)
