Registry-Integration Component: Implement InMemory variant

[FriedJannik]

Rules

• ConnectedAasEnvironment als dep
• In basyx.components (new folder in root)
• Existing implementation of registry-integration stays on the repository
• Registries should be specified (RegistrySpecification) as either a tuple of AasRegistry and SmRegistry or a single AasRegistry (smDescriptor will be saved in the AasRegistry)
• The component should keep track of where the AASs are stored -> Use CRUD Repository like in the other components

Acceptance Criteria

• Should allow configuration of multiple registries
• Should allow the specification of additional registries via a REST endpoint. E.g.:
  • createConnectedAas(Aas, RegistrySpecification)
  • createConnectedSubmodel(Submodel, RegistrySpecification)
