Provide a way to snoop the TLS connections with WireShark

[rgl]

To better troubleshot/debug the entire tinkerbell ecosystem we need a way to snoop the TLS connections (e.g. using the SSLKEYLOGFILE environment variable as in this go example) or a way to disable TLS.

The WireShark configuration is described at their Using the (Pre)-Master-Secret wiki page.

I see this as an opportunity for community members or maintainers if they use this techniques to blog about it.
Right now we have a not that detailed troubleshooting document that we can refer the blog post too. And an issue about Contrib documentation.

if you are working with Wireshark and you need some pointers from a Tink prospective reach out to me via Slack I am happy to collaborate on this.
