Instead of unwrapping furiously right away, this commit makes sky-bench
first run a ping test (HEYA) to check if everything is all right.
If that is the case indeed, then we continue to run the benches, else
we terminate the program.
This has been discussed in #119
This closes#107, closes#108 and closes#109.
The configuration template was updated to include TLS/SSL and the
corresponding tests were also updated.
It also renames `sdb` to `skyd` for streamlining binary names.
