Reorganize log messages pertaining to CLI arguments

Make it clearer when the CLI account/reservation is being parsed. I don't want
to refactor the config class to handle CLI arguments as an account (rather,
it will be handled after) as it would require a refactor and makes it much
harder to distinguish when the config parses an account/reservation in
the config file versus the CLI.
