[WIP] Keep a generic log of anonymized data

[toommz]

TODO

• Provide basic migrations see Oban
• Make logging optional
• Provide (hooks | behaviour) to decorate the log changeset with specific needs (anonymizing done in an async queue? add a status, requested_at and finished_at fields to the table structure and fill them with your own data)
  • may we return the log id in order to find it later from the async queue processing?
  • the {source_id, source_type} identifier tuple may serve as well to find it later

Table structure

id	source_id	source_type	serialized_changeset	inserted_at
1	2345	User	'{email,<<"redacted">>}'	2021-12-12-00:00:00

serialized_changeset can be created with:

:io_lib.format("~p", [email: "redacted"]) |> :lists.flatten()
