* .maintain/sentry-node: Add monitoring to docker-compose stack

With this patch a user can run the following fully configured and
monitored setup with a single command:

`docker-compose -f .maintain/sentry-node/docker-compose.yml up`

- 2 validators in two different network namespaces, connected via one
sentry node.

- Polkadot-js/apps to connect to one of the nodes above.

- Prometheus scraping the 3 Substrate nodes.

- Grafana displaying data from Prometheus with community dashboards

* .maintain/monitoring/grafana: Change default datasource name

* .maintain/monitoring/grafana: Add metric namespace option

* .maintain/monitoring/grafana: Remove `host` metric from most metrics

* .maintain/monitoring/grafana: Remove underscore from metric_namespace

* .maintain/monitoring: Use `instance` label instead of `hostname`

To identify a scrape target, one should use `instance` and not
`hostname` as multiple targets might run on the same node.

See https://prometheus.io/docs/concepts/jobs_instances/

 for details.

* client/authority-discovery: Add test ensure termination on network termi

* client/authority-discovery: Terminate when network does

When the dht event stream returns Poll::Ready(None) it is likely due to
the network terminating. When the network terminates due to the node
itself shutting down or due to a fatal error, there is no purpose in
continuing to run the authority discovery module.

* Add new RPC method to get the chain type

This adds a new RPC method to get the chain type of the running chain.
The chain type needs to be specified in the chain spec. This should make
it easier for tools/UI to display extra information without needing to
rely on parsing the chain name.
