* Fix mypy error with latest dask. Dask is adding type hints to its codebase and as the result, checks in XGBoost can be performed more rigorously. - Remove compatibility with old dask version where multi lock was missing. - Restrict input of `X` to be non-series. - Adopt latest definition of `Delayed`. - Avoid passing optional `host_ip`. - Avoid deprecated `worker.nthreads`.
