Subject: Add a "confidence" field about the reliability of the classification.
 (#1395)

As a general rule, the higher the confidence value, the higher the
"reliability/precision" of the classification.

In other words, this new field provides an hint about "how" the flow
classification has been obtained.
For example, the application may want to ignore classification "by-port"
(they are not real DPI classifications, after all) or give a second
glance at flows classified via LRU caches (because of false positives).

Setting only one value for the confidence field is a bit tricky: more
work is probably needed in the next future to tweak/fix/improve the logic.
