Add support for Function and Trigger domain objects (#1060)

Vast commit, includes: * Introduces the Trigger domain entity. * Introduces the Fns domain entity. * V2 of the API for interacting with the new entities in swaggerv2.yml * Adds v2 end points for Apps to support PUT updates. * Rewrites the datastore level tests into a new pattern. * V2 routes use entity ID over name as the path parameter.
