[Entity Store][Telemetry] Adjust current telemetry events include additional metadata

[uri-weisman]

Update the existing telemetry events to include additional metadata such as space_id and entity_type.
Additional fields may also be needed based on your findings and insights.

The current event-based telemetry includes:

1. Duration (in seconds) of the field retention enrich policy execution.
2. Duration (in seconds) of the entity store data view refresh.
3. Entity engine initialization failure.
4. Duration (in seconds) of the entity engine initialization.
5. Number of entities stored in the entity store (currently without entity_type).

For events 1–5, we can add the space_id, and for number 5, adding entity_type would also be valuable.
