Add support for activity expiration to common and Masto API

The "expires_at" parameter accepts an ISO8601-formatted date which
defines when the activity will expire.

At this point the API will not give you any feedback about if your post
will expire or not.

- `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_on`: datetime (iso8601), sets when the posted activity should expire. When a posted activity expires it will be deleted from the server, and a delete request for it will be federated.
