METRON-1065 grok pattern for cisco asa parser expects syslog pri ## Contributor Comments Cisco ASA logs does not always contain a priority code at the beginnen of the event. Therefore I've changed the grok pattern to make this optional. `<164>Aug 05 2016 01:01:34: %ASA-4-106023: Deny tcp src Inside:10.30.9.121/54580 dst Outside:192.168.135.51/42028 by access-group "Inside_access_in" [0x962df600, 0x0]` <164> should be optional. ## Pull Request Checklist Thank you for submitting a contribution to Apache Metron.
