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.
