In this patch, we can now make use of MicroStash only and
drop dead code.
At this point, we're sure that there are no captchas in the
main stash, freeing up this memory for other requests to use.

ConfirmEdit uses MainStash as the backend to write its captchas. We
are migrating this extension to use the MicroStash store instead which
is more suitable.
This patch will store the captcha in MicroStash, read it from there
or fallback to MainStash if lookup was not successful. The code will
then clear both stores once after processing.
Migration plan
==============
step .1: Write to microstash store only, read from it or
fallback to mainstash store. Then delete from
both backends.
step .2: Read from microstash store only, delete from the
microstash store, and remove dead code afterward.

This lays some groundwork for migrating from the main stash to a future
stash that resides in the primary datacenter.
