Example of Syslog triggered fetch

'syslog.rb' listed to UDP port (or reads file). When IOS or JunOS style
config change/commit message is seen, it triggers immediate update ot
config

It transports commit message (junos) remote host from which change was
mde (ios) and who made the change (junos+ios). This is carried over to
the 'output' methods, that is, 'git blame' will show IOS/JunOS user-name
who made the change.
