disable TLS handshake info in payload capture

[iapaddler]

When using TLS connections we are picking up the handshake content as well. While this might be useful in some cases we need to have a switch to not output this content

My preference would be to have this option off by default and allow users to turn it on if desired

To reproduce:

run the following command
SCOPE_PAYLOAD_ENABLE=true ./scope curl -v --http1.1 https://cdn.cribl.io/dl/latest

Look at one of the .in or .out files that are output in tmp

See below for an example of how the request looks like

Design discussions regarding LogStream indicate that LS will require the TLS exchange in support of protocol detection. Therefore, current thinking is to remove the TLS exchange when emitting payload data to files, but keep it intact when connected to LS.

Sort of getting close. Sending a request and extracting encrypted payload without TLS.
