Waiting 10s BEFORE discovering bootstrap nodes?

[alanshaw]

Shouldn't we discover on start instead of setting an interval and initially discovering after 10s? Looks like this is the main issue behind ipfs/js-ipfs#1706

js-libp2p-bootstrap/src/index.js

Lines 35 to 49 in eb2d882

	this._timer = setInterval(() => {
	this._list.forEach((candidate) => {
	if (!isIPFS(candidate)) { return log.error('Invalid multiaddr') }
	const ma = multiaddr(candidate)
	const peerId = PeerId.createFromB58String(ma.getPeerId())
	PeerInfo.create(peerId, (err, peerInfo) => {
	if (err) { return log.error('Invalid bootstrap peer id', err) }
	peerInfo.multiaddrs.add(ma)
	this.emit('peer', peerInfo)
	})
	})
	}, this._interval)

Here we set an interval, which triggers initially after 10s.
