Review comment:
I discussed this dependency issue with @kevdoran and he suggested this -imo- neat idea.
The `provided` scope is to _not_ introduce the swagger dependency to _nifi-api_ build time. With this we can avoid having it on the root classpath.
The run-time burden falls to the referring modules indeed but that shouldn't be a big issue. nifi-registry already had this obligation and the nifi-framework bundle also depends on swagger-annotations.
Considering only 2 high-level api annotations are used in nifi-versioned-components I think this is the best compromise we can get.
As for why even add this change _here_. The change in this PR was originally part of https://github.com/apache/nifi/pull/5118 and I'm now separating it from the Flow Analysis change as you suggested.
So the Flow Analysis change would follow this one soon. And I'd rather have this nifi-api -> nifi-versioned-components added in this one rather than that one as it has more general - we make those classes part of the public API. That is the purpose of this new module in the first place.
