Fix incorrect type declaration

[paulerickson]

what

• Correctly indicate types in variable definition

why

• There are number, bool, string, and list attributes, but the type is map, which can only contain values of a single type, so type checking prevents configuring custom_origin_config

example errors

With explicit tomap

Error: Invalid function argument
  on main.tf line 131, in module "router":
 131:       custom_origin_config = tomap({
