Revise real world example

[eyalb181]

• The example doesn't currently support clusters with service mesh, because port-forward requests arrive via localhost, which we ignore in iptables.
  • One way to solve this would be adding NGINX in front of the blog, and accessing it that way.
• We use too much custom configuration, e.g. mirrord exec --fs-mode local -x NODE_ENV --target pod/example-blog-- yarn -- workspace blog dev.
• The third step (Traffic Stealing) is unclear - why does it fail initially? What does the fix do?
• The example should mention the IDE extensions

The example should mention the IDE extensions

In my opinion we should take the readers by the hand, help them install the IDE extension as part of the example, and then do some cool stuff like set off a breakpoint by sending a request to the cluster.
I think having people try out the extension is helpful for making them like mirrord, and I think having them install the plugin as part of the tutorial would increase the chances they use it again later.
