* ci: use same feature set in `build_dev` and `build_release`
* ci: also enable unstable tokio for `build_dev`
* chore: update tokio to 1.21 (to fix console-subscriber 0.1.8
* fix: "must use"
* feat: detach dedicated exec jobs
* feat: async `DedicatedExecutor::join`
Now `DedicatedExecutor` follows the system we use for other server
components:
- `shutdown`: a quick sync call that signals the shutdown but doesn't
drop
- `join`: async awaits until the executor has finished shutdown
- `drop`: warn but still try to shut down
* test: irmpove `detach_receiver` test
