For the curtin side, the plan is to do two things.

1) update the dname for bcache to use the backing device's dev.uuid value and emit a symlink pointing to a /dev/bcache/by-uuid path. This gives us

/dev/disk/by-dname/<name> -> \
   ../../bcache/by-uuid/<dev.uuid> -> \
        ../../bcacheX

2) curtin will now echo the dname value into /sys/class/block/bcacheX/bcache/label which will
then enable /dev/bcache/by-label/<dname> -> ../../bcacheX

This work needs to be tested on Trusty -> Bionic; I'll work on updating the vmtests for bcache devices to exercise this path.
