[Bro] specific logging per worker

Hi Johanna, Thanks for the info,  I have 1 worker up at the border
inspecting everything and another worker below a few firewall and IPS
systems. i have just installed another worker below all these inspection
points but because all workers feed into a SIEM there no need for the likes
of the conn.log etc to be logging as much as it is off the same link
duplicated into the SIEM as its charged based on consumption.

So if we had a worker below our inspection points only logging some of the
log types we would still get the security benefit of having a worker placed
there without the storage requirements.

Thanks John
