Description of problem:
PA GUI sorts reverse DNS alphabetically rather than numerically

Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:
adding reverse DNS zones in IPA GUI

Actual results:
When looking at reverse DNS zones in IPA GUI, it sorts the IP addresses
(numeric) in an alphabetical order, leading to 1, 10, 100... rather than 1, 2,
3, ... 10, 11, ... and so on. This makes no sense. Reverse DNS zones, where the
keys are numeric, should be sorted numerically.

Expected results:
to sort the zones in a numerical order
