MINOR: ssl: Dump ciphers and sigalgs details in trace with 'advanced' verbosity

The contents of the extensions were only dumped with verbosity
'complete' which meant that the 'advanced' verbosity was pretty much
useless despite what its name implies (it was the same as the 'simple'
one).
The 'advanced' verbosity is now the "maximum" one, using 'complete'
would not add any extra information yet, but it leaves more room for
some actually large traces to be dumped later on (some complete
ClientHello dumps for instance).
