[PATCH 3/6] BUG/MINOR: spoa/python: Ensure ip address references are freed

[gilchrist]

From: Gilchrist Dadaglo <dada...@amazon.com>

IP addresses references passed in argument for ps_python are not freed after 
they have been used.
Leading to a small chance of mem leak if a lot of ip addresses are
passed around
