Increase burst delete limit in Transaction and TCP connections tables

Currently, burst delete limit for Transaction and TCP tables is lower than the packet period after which timeout procedure is triggered. This can lead the tables to gradually fill up because they might not be able to timeout the records fast enough if influx of bogus queries without responses is too large. That in turn might limit probe's ability process traffic.

This MR sets burst delete limit for Transaction and TCP connections tables to the same value as packet period for timeout procedure (1024) which should give the tables the ability to timeout records fast enough to not fill up.
