Lingering global flags

[bobvawter]

There are still some old flags declared as globals (schemawatch.RefreshDelay is one) that aren't wired up to the CLI commands. We should checks for any dangling flags and ensure they're registered.

@bobvawter is the ask here to deprecate these and remove? Or to make sure we wire them up to the CLI?

[bobvawter]

Not all of the older packages currently define a configuration object (e.g. staging/stage). I think the work is really to ensure there's a consistent way to define configuration types and ensure that they're correctly wired up without creating a situation where irrelevant flags are exposed on the various CLI command objects.
