The latest libp2p release allows services to declare their capabilities (what they provide to the node) and their dependencies (the capabilities they require other services to provide for the config to be "valid").
Adds the
serviceCapabilities
symbol property that says Gossipsub provides the@libp2p/pubsub
capability and also theserviceDependencies
symbol property that says it depends on some service providing the@libp2p/identify
capability - this is required because Gossipsub uses network topologies to discover peers which requires the Identify protocol.
