Subject: T4904: keepalived virtual-server allow multiple ports with fwmark

Allow multiple ports for high-availability virtual-server
The current implementation allows balance only one "virtual" address
and port between between several "real servers"
Allow matching "fwmark" to set traffic which should be balanced

Allow to set port 0 (all traffic) if we use "fwmark"
Add health-check script

  set high-availability virtual-server 203.0.113.1 fwmark '111'
  set high-availability virtual-server 203.0.113.1 real-server 192.0.2.11 health-check script '/bin/true'
  set high-availability virtual-server 203.0.113.1 real-server 192.0.2.11 port '0'
