Shared memory across multiple machines to the heavy AJAX lookups.

Select2 uses django.core.cache_ to share fields across
multiple threads and even machines.

Select2 uses the cache backend defined in the setting
``SELECT2_CACHE_BACKEND`` [default=``default``].

It is advised to always setup a separate cache server for Select2.
