[FR] Monitor core.entity_registry for “orphaned” entities

[ildar170975]

Sometimes core.entity_registry contains entries for deleted entities. Usually it happens due to bugs in corresponding integrations. These entities are not displayed in the Settings - Entities list.
IMHO it would be great to monitor such entries.
Frankly speaking, I have no idea how to monitor it.
A user may find these “orphaned” entities while comparing that Entities list with the “core.entity_registry” file. But I believe that this Entities list is generated on this file, so I wonder how this file may contain these “orphaned” entities which are not displayed in the Entities list.
