Unexpected failed to connect to bootstrap nodes warning

[StephenButtolph]

Avalanchego will incorrectly report that the beacon nodes are unreachable when running a node with reduced performance.

avalanchego/node/node.go

Lines 622 to 625 in 41e46d1

	n.Log.Warn("failed to connect to bootstrap nodes",
	zap.Stringer("bootstrappers", n.bootstrappers),
	zap.Duration("duration", n.Config.BootstrapBeaconConnectionTimeout),
	)

This issue is able to be replicated consistently on nodes with high performance by extending the time to initialize the platformvm.

For example, modifying

avalanchego/vms/platformvm/vm.go

Line 108 in 41e46d1

chainCtx.Log.Verbo("initializing platform chain")

. To:

+	time.Sleep(time.Minute)
+
	chainCtx.Log.Verbo("initializing platform chain")
