Facilitating Strategy pattern using Spring Plugin library

This is an example of Spring Plugin library applied to an Hexagonal Architecture use case where we're required to introduce another repo implementation that runs in tandem with the existing one.

One of the requirements is to vary the order of execution between implementations, e.g. first db, then http, etc.

This video helped me discover this great library.
