Jon Siwek 35827eeb31 Add rate-limiting sampling mechanism for weird events
The generation of weird events, by default, are now rate-limited
according to these tunable options:

  - Weird::sampling_whitelist
  - Weird::sampling_threshold
  - Weird::sampling_rate
  - Weird::sampling_duration

The new get_reporter_stats() BIF also allows one to query the
total number of weirds generated (pre-sampling) which the new
policy/misc/weird-stats.bro script uses periodically to populate
a weird_stats.log.

There's also new reporter BIFs to allow generating weirds from the
script-layer such that they go through the same, internal
rate-limiting/sampling mechanisms:

  - Reporter::conn_weird
  - Reporter::flow_weird
  - Reporter::net_weird

Some of the code was adapted from previous work by Johanna Amann.
