To have accurate measurement of TLS and support skipped steps (DNS, TCP
and TLS reuse), the timing code has been refactored to use Go 1.8
support for TLS tracing as well as a more descriptive variable namings
for steps time.

This commit removes support for Go versions lower than 1.8.

As explained in the previous comment, this PR is based on #128. I'm waiting for it to be merged before rebasing on master.

I sent this PR to share a feature I added for my own use. There is no issue associated, it fixes nothing. I can open a separate issue if it's the way you want it.
