[feature] ActivityPub federation

[hex-m]

Some community-focused social platforms started adopting a common protocol so users on different platforms and servers can interact with each other. This would most likely be a very big change to the architecture.

What's the reward:

1. Different people/organizations can host their own BeWelcome-Server but the users can still communicate with everyone (like we know it from e-mail servers). This also means the network is less dependent on a central server/operator.
2. Users are able to contact their friends on other supported platforms. e.g. Mastodon (~twitter), Peertube (~YouTube), Nextcloud (~Dropbox)

I support this feature. I would love to see ActivityPub implemented on the Activity part of BW. Check at what Framasoft is doing: https://joinmobilizon.org It wold be great to let BW user to create public event that would be available to the federated network.

ActivityPub provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and subscribing to content.
