Minor code cleanup
Rework how we set SOA attributes

Reorder code for the two domain zones to be in similar order
Convert the attribute for records to a hash instead of referencing it

Since we are putting the final zone mash in the attribute, if we just
reference the records, then we will save a reference to the records
instead of something different.

This will be an issue soon, since we will compare the zones from the
attribute to the zone we're rebuilding to see if there's a change.
Only increment serial for DNS zones when there's a change

Instead of incrementing on every chef run, we compare the zone with what
was saved in the attributes, and if there's a difference, we bump the
serial.
