Detect OpenFeign, Retrofit or OkHttp on classpath and use those instead

[iamareebjamal]

OpenFeign or Retrofit are generally included to create REST API consumers along with OkHttp3 which has a better performance and API than HttpUrlConnection

I am not too sure how I would go about doing this. How can I detect these on the classpath without including them as a dependency?

These won't be transitive dependencies. And would be provided by the developer when including the library. This can be taken later on as its just an enhancement
