Bug Description

<hallyn> if you interrupt lxc-create, it *will* clear out the container. but not the cache

===============================
SRU Justification:
1. Impact: interrupting a first container build can cause later builds to fail
2. Development fix: clear the cache if a build is interrupted during cache build.
3. Stable fix: same as development fix
4. Test case: start creating a container, ctrl-c it during cache creation (i.e.
during wget), then re-try.
 sudo lxc-create -t ubuntu-cloud -n p1
 [...] ctrl-lc
 sudo lxc-create -t ubuntu-cloud -n p1
5. Regression potential:
   This changes code in the ubuntu, ubuntu-cloud, and debian templates, and
   therefore could cause bugs in container creations.

===============================

(To be clear, of course it should only clear the cache if interrupted while filling in the cache)

I think this would be worth fixing in precise.
