Merge lp:~jameinel/maas/1.2-remove-kernel-opts into lp:maas/1.2

[John A Meinel]

This removes the recent patches to add kernel_opts to the 1.2 branch.

We'll land it instead on trunk, and then it will get backported in the future once a bugfix only SRU was done.

(Original proposal accidentally targetted trunk, this is now properly targetting 1.2)

[Martin Packman (gz)]

Nothing obviously bad. Removing a schema migration is a little dodgy, but I guess we just tell anyone with a 1.2 development branch that they need to `rm -rf db && make syncdb`.
