[BUG] Submodel Sharing

[schwens-iff]

Describe the bug
I encountered this bug while trying to share a submodel between 2 AAS.
First of all this feature is not implemented. Second, using a hack in the UI caused multiple the AAS to become corrupted.

To Reproduce
Steps to reproduce the behavior:

1. Create a new Submodel in an AAS
2. Copy the ID of the new Submodel
3. Create a new Submodek in a second AAS using the copied ID
4. An error will occur, regardless the Submodel will added to the AAS
5. Exporting both AAS will output a file that contains the log of an internal Server Error
6. Deleting the Submodel in the first AAS will leave behind a fragment in the second AAS
7. The fragment in the second AAS cannot be deleted
8. Exporting the first AAS will work, exporting the second will throw an error in the UI

Expected behavior
Feature to add an existing Submodel as menu point under 'create submodel'
Export without errors.
Feature to remove an Submodel from an AAS.
Deleting an Submodel will remove all references of it in all AAS or the the ability to remove Submodel fragments.

Hello @schwens-iff, you are right, this is not yet implemented and will be added in a later release of the BaSyx AAS Web UI. Thanks for adding this feature request. We will come back to this
