[question/daisy] Why no region parameter?

[gut]

I'm implementing ForwardingRule step on daisy as requested on #437 (comment) but I see that daisy is not ready for using region as a parameter. In order to implement it I thought about:

1. Implicitly define it from zone when needed (basically region = zone[:-2])
2. Add a parameter -region to be passed by command line for supplying that information, otherwise a valid error like no region provided in step or workflow might occur.

What's your opinion on this?

I like the idea of implying the default region from the default zone, we may also want a top level Daisy default in the worklfow/flag too as I believe I made zone optional. Technically you could just be working with regional resources so demanding you specify zone doesn't make sense.

Working only with regional resources? I always instantiate a machine so I always needed to define a zone.

I can implement this later, but for now, please check the first approach I implemented on #434 , specifically c9f1884#diff-7b1669af81e6327ae6d38b7c32b4003bR57

well, It's working thanks to #434. I'll soon make use of it again for managing subnetworks on daisy so I guess this task can be closed for now
