Rebrand recipe module to rewrite-feature-flags

[timtebeek]

What problem are you trying to solve?

Would like to align this module more closely to rewrite-logging-frameworks and rewrite-testing-frameworks, each of which cover various implementations. That way we can more easily cover additional libraries like OpenFeature or Togglz without confusion or overhead.

Describe the solution you'd like

Rename module, rename package, introduce separate package for openfeature, do new release.

Have you considered any alternatives or workarounds?

1. A separate module per technology: would result in a lot of overhead.
2. A multi module repository: would result in better separation of classpath dependencies, but also additional overhead.

Agreed internally to rebrand; will schedule when time allows.
