* test(cli): add basic coverage to test cli help output
- Add basic coverated when invoking the command without arguments
- Basic checks for grafana help
* feat(cli): delegate command line options configuration to the Grafana plugin
It uses the name of the plugin as a namespace for all options. Plugin authors _may_ use this
in the future to show helpful messages in the default sitespeed CLI help output.
- Move CLI options to its own module to not pollute the plugin's `index.js` file.
- Change the plugin interface to define a `.cliOptions` property or method containing the `yargs`
configuration to be used by the CLI code
- Add code coverage for the existing plugin API to ensure no regressions are introduced for Grafana
- Move parts of the `yargs`-related code to `cli/util.js`. Tests to ensure the initial proposition for
plugin-based CLI options are included.
