MEDIUM: log: add the ability to include samples in logs

Using %[expression] it becomes possible to make the log engine fetch
some samples from the request or the response and provide them in the
logs. Note that this feature is still limited, it does not yet allow
to apply converters, to limit the output length, nor to specify the
direction which should be fetched when a fetch function works in both
directions.

However it's quite convenient to log SSL information or to include some
information that are used in stick tables.

It is worth noting that this has been done in the generic log format
handler, which means that the same information may be used to build the
unique-id header and to pass the information to a backend server.
