First, I don't think RollingUpdatePattern and CanaryUpdatePattern should be 2
different entities. The second just looks like a parametrization of the first
(growth_factor=1?).
Perhaps they can just be one. Until I find parameters which would need
to mean something different, I'll just use Upda

Quick thoughts:
- I'd like to be able to express a minimum service percentage: e.g. I
know I need 80% of my capacity available at anyone time, so an
additional constraint to the unit counts, is to stay below 20% down at
a time (and this implies that if 20% have failed, either stop or spin
up more
So, I wrote the original rolling updates spec about a year ago, and the
