Combo pr for testing / draft review

https://wandb.atlassian.net/browse/WB-20784

This pr:

• adds a flexible obj_delete api that can delete specific versions of an object, or all versions of the object.
• server api inserts an object with identical primary keys and a deleted_at field. Before insert, we read from the db, and insert the full data payload, ensuring no data is lost. ReplacingMergeTree deduplicates at merge, keeping the latest version of each row grouped by the primary (order by) key.
  • "The most recently created part (the last insert) will be the last one in the selection. Thus, after deduplication, the very last row from the most recent insert will remain for each unique sorting key." link
• updates the read path to filter out objects with deleted_at set.
• the client in this pr catches the deleted object error when de-reffing nested objects, instead of throwing.
• adds a trash button to the object versions page
• updates the objects query to refetch on delete

TODO:

• add restriction on deleting object versions to no more than 100 at a time -- we do read the val_dump here so its important to add a sane limit.
• investigate performance implications for massive data deletion requests. Example: try to delete an object with 100,000 versions. This should be fine without batching, as we do an objects query without grabbing val_dump, and deletion occurs as an insertion.

Api usage:

api = weave.init()
obj = obj.get()

# delete a single version of an object
api.delete_object_version(obj)
# delete all versions of an object
api.delete_object_all_versions(obj.object_id)

Depends on:

• server pr
• types pr
