Support multiple instances of responses and dio clients for a single project

[jr-rootstrap]

At the moment that an initial configuration is made on the Dio client supporting a base configuration of a client (RGB in this case) and this same is changed to customized responses that come from a middleware (that is not from the client), and the base responses notoriously change the result of the operations and interaction of responses.

Currently, the solution that can be proposed on the basis is that it is not necessary at all to inject another instance of Dio on the project and then make adaptations of the base response created vs. what was created at the beginning of the configuration.

The idea of this approach is to consider that it would be of less impact for the base network layer to do this, and raise a PR with a possible solution.
