Make identify-push autodial smarter

[wemeetagain]

Description:

Imagine this scenario:

// MyApp has 10 protocols that get enabled once some event happens
class MyApp
  libp2p: Libp2p

  static async init(): Promise<MyApp> {
    return new MyApp(
      await createLibp2p({
        streamMuxer: mplex(),
        services: {
          identify: identify()
        }
    )
  }

  ...

  onSomeEvent(e) {
    await Promise.all([
      this.libp2p.handle('protocol1', ...),
      this.libp2p.handle('protocol2', ...),
      this.libp2p.handle('protocol3', ...),
      this.libp2p.handle('protocol4', ...),
      this.libp2p.handle('protocol5', ...)
      ...
    ])
  }
}

This innocuous app will likely drop all connections to peers that accept identify-push when the 'some event' happens.

• Each call to libp2p.handle updates the local peer store, and triggers a separate identify-push.
• These identify-push streams are locally opened and closed quickly.
• Receiving peers receiving a bunch of spammy identify-push requests will send back stream resets.
• These stream resets will appear to the local node coming from "unknown stream ids" and will blow the rate limiter limit, triggering a connection close.
