- ActivityPub: Deactivated user deletion
### Added
- Expiring/ephemeral activites. All activities can have expires_at value set, which controls when they should be deleted automatically.
- Mastodon API: in post_status, the expires_in parameter lets you set the number of seconds until an activity expires. It must be at least one hour.
- Mastodon API: all status JSON responses contain a `pleroma.expires_at` item which states when an activity will expire. The value is only shown to the user who created the activity. To everyone else it's empty.
- Configuration: `ActivityExpiration.enabled` controls whether expired activites will get deleted at the appropriate time. Enabled by default.
- Conversations: Add Pleroma-specific conversation endpoints and status posting extensions. Run the `bump_all_conversations` task again to create the necessary data.
- **Breaking:** MRF describe API, which adds support for exposing configuration information about MRF policies to NodeInfo.
Custom modules will need to be updated by adding, at the very least, `def describe, do: {:ok, %{}}` to the MRF policy modules.

- `content_type`: string, contain the MIME type of the status, it is transformed into HTML by the backend. You can get the list of the supported MIME types with the nodeinfo endpoint.
- `to`: A list of nicknames (like `lain@soykaf.club` or `lain` on the local server) that will be used to determine who is going to be addressed by this post. Using this will disable the implicit addressing by mentioned names in the `status` body, only the people in the `to` list will be addressed. The normal rules for for post visibility are not affected by this and will still apply.
- `visibility`: string, besides standard MastoAPI values (`direct`, `private`, `unlisted` or `public`) it can be used to address a List by setting it to `list:LIST_ID`.
- `expires_in`: The number of seconds the posted activity should expire in. When a posted activity expires it will be deleted from the server, and a delete request for it will be federated. This needs to be longer than an hour.
- `in_reply_to_conversation_id`: Will reply to a given conversation, addressing only the people who are part of the recipient set of that conversation. Sets the visibility to `direct`.
