Custom Retriever

To create a custom retriever you must have a struct that implements the Retriever interface.

type Retriever interface {
	Retrieve(ctx context.Context) ([]byte, error)
}

The Retrieve function is supposed to load the file and to return a []byte of your flag configuration file.

You can check existing Retriever (file, s3, ...) to have an idea on how to do build your own.
