Support task dependency about funnel HOT 5 CLOSED

This is related to #38 and we're looking at building this into the funnel client CLI as funnel wait and funnel run --wait.

I'd be interested in learning about cases where handling this client-side isn't good enough though.

#98 added funnel run --wait and funnel wait. #105 will further refine this.

I don't expect we'll be implementing this on the server side in the near future.

Cases where client-side isn't ideal:

• Close laptop (have to run the client on a VM at addl cost)
• Complex graph where a blocking funnel task wastes cpu cycles (in theory, maybe not in practice)
• The backend already supports server-side dependency
• The backend can display DAGs only if the tasks are all submitted up-front without client-side blocking

That said, client-side is really not too bad :)

Great, thanks for the insight. Being able to close your laptop seems important. Possibly we can do this on a per-backend basis: if the backend supports dependency, we can consider using it.

I have some experimental task dependency code here, which might be a good starting point if we ever want to do this in Funnel: https://github.com/buchanae/ktl
