This was an intentional design to depend on dogpile.cache due to the
mechanism of caching (using decorators).  This is partially the nature of
the method of caching implementation.  It should have been installed in
devstack based upon the requirements.txt having it in there.  Making it an
optional import is likely going to take a significant amount of
refactoring.  My guess is that it's going to be a bit late in the cycle,
but we will see what comes up.
