Original issue from the substra repository
It is possible to create an aggregatetuple without passing any --in-model-key in the command.
Issue in the backend
The in_models_keys field of an aggregatetuple isn't required and has a minimum length of 0.
As the sole purpose of the aggregatetuple is to aggregate at least 2 models together, the in_models_keys should be required and should have a minimum length of 2.

@maeldebon following the short discussion we've had in the PR, I'm moving this issue to the backend repository.

As said in the backend PR, there is no reason for adding this restriction. Aggregating nothing or aggregating a single model should be possible.
