Merge lp:~hopem/maas-deployer/lp1491443 into lp:~maas-deployers/maas-deployer/next

Why don't we do a switch 'fail on error', instead of catching every maas call that we should fail on?

[Edward Hope-Morley (hopem)]

I think we can look into that for the next release. If we implement that kind of logic we have to take a close look at the code to make sure we don't get false positives etc. Basically i think to get that right it will be nontrivial so lets punt it to 0.0.3
