POC of header downloader - splitting into 2 processes: sentry + downloader (via gRPC) (#1291)
* Splitting sentry and downloader - the beginning

* A bit more

* More on sentry

* More gRPC

* Sentry and downloader separated

* Update binding for stable version of grpc

* Better bufferSize flag

* Fix lint

* Send pelanties

* Fix lint

* Remove hard-coded tips on connect

* Tidy the logs a bit

* Deal with hardTips on Recovery

* Print hard tips

* Hide empty anchors

* Request headers after receiving a message

* Better waking up

* Print hard-coded block numbers

* Print outgoing requests

* Debug logging

* In the middle protection

* Sentry not to lose peers when core disconnects
