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.
