Feather-ws rewrite; - Move recurring tasks into their own class; inherits from `FeatherTask` - CCS proposals: Don't use API, it's broken - webcrawl instead until it is fixed. - Switch to hypercorn as the ASGI server, *with* support for multiple workers. You can now run feather-ws with, for example, `--workers 6`. See `Dockerfile`. - Introduce support for various coins under `BlockheightTask` - Introduce support for various Reddit communities under `RedditTask` - Introduced weightvoting whilst validating third-party RPC blockheights - where nodes are filtered based on what other nodes are commonly reporting. - Current blockheights are fetched from various block explorers and weightvoting is done to eliminate outliers under `BlockheightTask`. - Don't filter/remove bad nodes from the rpc_nodes list; correctly label them as disabled/bad nodes. - Multiple Feather instances (each for it's own coin) can now run on one machine, using only one Redis instance, as each coins has it's own Redis database index. - Configuration options inside `settings.py` can now be controlled via environment variables. - Better logging through custom log formatting and correct usage of `app.logger.*` - Fixed a bug where one task could overlap with itself if the previous one did not finish yet. This was particularly noticable inside the `RPCNodeCheckTask` where the high timeout (for Tor nodes) could cause the task to run *longer* than the recurring task interval. - Introduced a `docker-compose.yml` to combine the Feather container with Redis and Tor containers. - Blocking IO operations are now done via `aiofiles`
