Instead of passing a context around to each method, thereby introducing
side-effecting I/O actions everywhere, with this PR `sync::ChainSync`
only contains state which is updated by invoking various callback
methods (`on_*`) and actionable items are returned as regular results
from method calls, often iterators yielding requests that should be
issued to peers. It is up to the caller to handle these in an
appropriate way, currently `protocol` will send those as messages.

Given the following situation: A validator 'A' is not supposed to be
connected to the public internet to protect it from e.g. a DoS attack.
Instead it connects to a sentry node 'sentry-A' which connects to the
public internet. Validator 'B' can reach validator 'A' via sentry node
'sentry-A' and vice versa.

A sentry node needs to participate in the grandpa gossip without
becoming a validator itself in order to forward these message to its
validator. This commit adds a new command line flag (`--grandpa-voter`)
forcing a node to participate in the grandpa voting process even though
no `--key` was specified. Due to the fact that it does not have a key,
it does not become a validator in the network.

In order to simulate the above situation this commit also adds a Docker
Compose file (`scripts/sentry-node/docker-compose.yml`) with further
documentation.
