Refactored enterprise unlink code to fix ENT-1890
Fixed quality violations and brokent test
Fixed pylint quality violations
Fixed failing unit test
Fixed broken test after rebasing with master
We need to do this because when I tride to go to the JSON serializer a
bunch of tests started failing because various parts of our code are
putting things into the session that are not JSON serializable.
We can't keep using the default pickle serializer because it defaluts to
using the highest available protocol and that will cause issues with the
python 2 to 3 upgrade since both will be running in production at the
same time. We need to use a version of the pickle protocol that both
can use interchangably.
We also need to make sure we read with latin1 encoding to make datetimes
work correctly between the two versions of python.
HIGHEST_PROTOCOL will cause it to change when we move from python 2 to 3
and this may cause issues as older machines try to read objects pickeld
with a version of the protocol they don't know.
During deploys, and if we have to roll back are two examples.
