the limit match limits the rate at which a rule will match.

the rule will match the average number events per time period specified
by "--limit", but may match up to "--limit-burst" number of events
initially, and for every "--limit" time period that passes without
a match.

it is most commonly used in rules to (a) throttle the volume of logging
that can take place and (b) protect from SYN floods.
