v0.21.0

## ⚠️ Breaking Changes

### Protocol Changes

- iroh-relay
    - Clients will dial `/relay` instead of `/derp`, this means all `0.21` nodes are only compatible with relays `>= 0.20`

### API Changes

        - `tag` -> `tags`
        - sub commands
            - `new` -> `create`
    - added `metrics_dump_path` on the top level CLI parameters, which if set will make sure metrics are collected at regular intervals and written to the provided path in CSV format.
- `iroh`
    - removed deprecated
        - `client::MemIroh` use `iroh::client::Iroh` instead
        - `client::QuicIroh` use `iroh::client::Iroh` instead
        - `client::MemDoc`use `iroh::client::docs::Doc` instead

        - field: `magicsock::metrics::Metrics::update_endpoints` -> `update_direct_addrs`.
    - relay server is now behind the `iroh-relay` feature flag
    - removed
        - `endpoint::Builder::peers_path`
    - added
        - `endpoint::Builder::known_nodes`
- no automatic storage of known peers anymore in `iroh-net`
