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.

This will force a logout as sessions fail to load but this should be a
more performant and secure serializer moving forward.  The reason we
overwrote it in our config is that it previously used to be the default
and we didn't want things to breake and force logouts when we changed
it.  We're no more okay with people getting logged out.

Added new variables from configuration repo

Add stable_bucketer helper tool

* explicitly setting strings to unicode

Minor changes to CODEOWNERS file.

move the anonymous check earlier so that it cannot error out when it …

Pre-select the course overview during dashboard loading

DescriptorWithMixins are dynamically created and do not have a hash
class method. Those classes had hash values in python2 but do not
have a default hash in python3. Thus those class objects can not be
used as dict keys. Used location of section/unit instead of real object
for cache dict. Location object is hashable.
