When is removed by the host itself, the host's daemon should modify its file in the common bucket, changing the HostConfigured section to indicate that the host is no longer present in the network.

All other hosts in the network, when a host is updated with an indication that it's no longer present in the network, should add that host's certificate fingerprint to the pki.blocklist of their local nebula instance.

The pki.disconnect_invalid boolean should always be true in the nebula config.
