Allow for associating multiple queries with single system.

Describe the problem you are trying to solve. In some scenarios it might be useful to iterate multiple queries in a single system. Currently an application can store queries in a component and access those from a system, but this has as downside that the scheduler is not aware of the components read/written in those queries.

Describe the solution you'd like Add builtin component that allows for storing multiple queries that is interpreted by scheduler.
