add_hydra_models_to_config_store customizable group names

Have the possibility to change group-names using a simple dictionary keyword. At the moment one can only use the default group names, but imagine you want to use the "distributions" group as "latent_space" in your code. I imagine this can be simply done adding something like this:

cs = add_hydra_models_to_config_store(cs, rename_groups{"distributions": "latent_space"})
