Allow selection of TLS ciphers and options (+ show debugging info in console)

[shamasis]

Currently, Postman App does not show helpful debugging information regarding SSL /TLS protocol configuration / state during request and response. As such, it is difficult to distinguish between Postman issues vs handshake issues. Additionally, the TLS configurations and ciphers are not tweakable and as such, results in some specific requests to fail or negotiate an unexpected TLS version.

1. Add additional configurations in protocolProfileBehaviour to control TLS
2. Show TLS debug information in console (or somewhere else.)

the TLS configurations and ciphers are not tweakable

ciphers are configurable by CLI or programmatically:

• https://nodejs.org/api/cli.html#cli_tls_cipher_list_list
• ciphers option of https://nodejs.org/api/tls.html#tls_tls_createsecurecontext_options

What specific configurability are you looking for?

Show TLS debug information in console

Is nodejs/node@5b55c60 what you are looking for? If so, I'll try to get something like it into node. Not sure if direct printf is OK, or whether a programmatic API that just callbacks the SSL_trace output to JS, and lets the user do with them what they will is the way to go. Do you have opinions?
