writeCompletionScriptForCommand method

@visibleForTesting bool writeCompletionScriptForCommand(String rootCommand)

Creates a configuration file exclusively to rootCommand and the identified shell.

The file will be named after the rootCommand and the current shell (e.g. very_good.bash).

The file will be created in completionConfigDir.

If the file already exists, it will do nothing.

Returns true if the file was created, false otherwise.
