[MaaS] destructive storage test fio on failure

[MaaS] destructive storage test fio on failure

Perform fio storage destructive test operation (usually takes just a
few minutes) to completely destroy any previous storage metadata that
might cause issues with cleanup in cloud-init/curtin during deploy.

Only resort to fio when a node fails to deploy, which allows us to
reuse the `maas.machines.mark_broken_state` state.
