OpenAppID: add new package

Traditionally, Snort rules are based upon packet analysis.  OpenAppID
enables detection of applications/cloud applications on the network.

This package provides OpenAppID and signature files used by OpenAppID to detect
network traffic from certain applications can be used to identify rogue
application use, detect malicious applications and implement various
application policies, such as application blacklisting, limiting application
usage, and enforcing conditional controls.

To use, for example, edit /etc/snort/local.lua and add the following section
at a minimum:

appid = {
  app_detector_dir = '/usr/lib/openappid',
  log_stats = true,
  app_stats_period = 60,
}
