rename operational configuration to application configuration (#98)

Per #95, this renames OperationalConfiguration (and all related terminology) to ApplicationConfiguration (with related terminology).

BREAKING CHANGE.

Closes #95

-A _trait_ is a discretionary runtime overlay that augments a component workload type (`workloadType`) with additional features. It is an opportunity for those in the _application operator_ role to make specific decisions about the configuration of components, but without involving the developer. A trait can be any operational configuration of a distributed application that applies to an individual component, such as traffic routing rules (e.g., load balancing policy, network ingress routing, circuit breaking, rate limiting), auto-scaling policies, upgrade strategies, and more.
