[Bro] Bro cluster requirements and manager logging backlog bug

Actually file rotation does work but it's prone to fail because of a
timestamp collision.  Each rotated file is named based on the timestamp
when the rotation started.. so they are about 10-20 seconds different in
name.  (ex: x509.22:51:59.. x509.22:52:20.. x509.22:52:30).  I guess the
fix would be to change the filenames relative to each logger, ex:
"logger-1_x509..." or something more clever like merging all logger files
into a single zip file.

A cluster-layout for 2 loggers is attached.  I don't think there's anything
to fix here based on the comments below.

When I configure 8 loggers only 3 loggers are working.  (logger-3,
logger-4, and logger-8).  I restarted the cluster and this time 5 of the
loggers are working.  (2,3,4,6,8).  Still looking into why this happens.
This problem would affect the Kafka export since each logger would be
exporting.  Restarting the failed loggers didn't fix the log flow.  It
looks like they are associating with the assigned logger correctly after
startup and there's nothing indicative in the worker logs stderr or stdout.
