Use hyper 0.11 in ethcore-miner and improvements in parity-reactor (#8335)

* parity-reactor: Pass over Handle in spawning fn to allow normal tokio ops

* Allow fetch to work with arbitrary requests

* typo: Fix missing handler closure

* miner, work_notify: use fetch and parity-reactor

* Fix work_notify pushing in parity CLI
