Disable memcache completely

Browse source 
We've determined that getting correctness semantics right, even
in the few cases that it is possible to do so (see linked bug for
audit) is not worth the bother in terms of highly complicated code
and potential bugs. This CL turns off memcache at the Ofy level
but doesn't rip out the annotations etc. so that we can quickly
turn it back on if this turns out to have been a mistake.
