hyperspace cores are not announced: hyperspace/server.js is not calling db.putNetworkConfiguration() anywhere

[KrishnaPG]

In the server.js the networker.configure() method (required for announce) is dependent on db.listNetworkConfigurations() (see below):

hyperspace/server.js

Lines 120 to 125 in 26d6d36

	async _rejoin () {
	if (this.noAnnounce) return
	const networkConfigurations = await this.db.listNetworkConfigurations()
	for (const config of networkConfigurations) {
	if (!config.announce) continue
	const joinProm = this.networker.configure(config.discoveryKey, {

However, no where in the server.js file the db.putNetworkConfiguration() is called, which means the db.listNetworkConfigurations() always returns empty, thus the cores are not announced.
