Block contract definitions with empty assetSelector

[rafaelmag110]

WHAT

Tractusx-edc should provide a feature that blocks the creation/update of contract definitions to contain
an empty asset selector.
This feature should have the option to be switched on/off, being off the default state.

WHY

The assetsSelector property is a query (similar to a SQL SELECT statement) that returns a set of assets the
contract definition applies to. When left empty, the default behavior of the connector is to apply the contract
definition to all registered assets.

Unwillingly, mostly due to lack of proper connector usage knowledge, users might expose datasets that shouldn't be
exposed.

STEPS

• Provide a decision record outline the decision to include such feature and explaining the approach
• Implement the decided upon approach
