Refactor route53 zones created for projects into new module

[arturtamborski]

again, more modules = more better!
route53_zone - as a module name?

I really wanted to do this nicely, but it turns out that terraform doesn't support for_each in modules... But it will in few months! - hashicorp/terraform#25016

So I guess this one is on hold until next release is out.

Can you provide more details regarding how you want to utilize for_each here?
