This commit fixes a couple bugs in the Netflow input causing flow loss in Netflow V9 and IPFIX: Due to an error the expiration loop was expiring the sessions twice in each iteration. This caused all the sessions to be expired wether active or not, every time that the expiration interval elapsed. The NetFlow input was mistakenly comparing sequence numbers (v9 and IPFIX) from the same source but different Observation Domain (aka Source ID). This caused the session to be reset when packets from different source IDs where interweaved. This refactors the source ID out of session and into the session key, so that now a different source ID from the same source creates a new session. (cherry picked from commit 62d0e87)
