Filter for new SubmodelDescriptors in the Registry

[sebbader-sap]

Use case: millions of entries in a Submodel/AAS Registry but the client application is only interested in the once created/modified/deleted since a certain point in time.

"point in time": Timestamp or numeric time value

see also #7 for more query parameters: the new parameter/solution should be consistent with the overall strategy for querying in the AAS Registry.

Consider RQL for quering in the AAS Registry

This seems similar to #346

We need to have a look at this after the 3.1 release.
