CLI: commands to create and edit workflows

[josephjclark]

There's quite a lot of local boiler plate needed to add, rename or remove workflows and steps

it would be nice to have CLI helpers for this:

openfn workflow add <workflow-name>
openfn workflow rename <old-name> <new-name>
openfn workflow remove <workflow-name>

By name I think I mean id, not really name. It might be nice to accept a name as a quoted string and slugify it. So I can do openfn workflow add "Fetch from DHIS2 😃" and it'll just work like it would in the app

There's a similar command for steps:

openfn step add <workflow-name> <step-name>
openfn step rename <workflow-name> <step-name> <new-name>
openfn step remove <workflow-name> <step-name>
openfn step link <from-step> <to-step>

The step API is pretty heavyweight as you need to specify the workflow. If there's only one workflow you could default it. Maybe it's more like

openfn step add <step-name> -w <workflow-name> 

Now workflow name is optional (but it's usually needed)

I'm not sure if this should be namespaced under project. Probably the logic lives in project. Maybe like checkout, it's a project function but we have a top level alias

The CLI helpers would only modify the local file system - they should not write back to the project.yaml files or anything
