Subject: check in for Bug 6959

Add the ability to run a user defined script to determine wan load-balancing interface health

includes sample http test (scripts/http_test.pl). Configuration will look as follows:

 wan {
     interface-health eth0 {
         nexthop 10.3.0.1
         test 1 {
             test-script /tmp/http_test.pl
             type user-defined
         }
     }
     interface-health eth1 {
         nexthop 10.3.0.1
         test 1 {
             test-script /tmp/http_test.pl
             type user-defined
         }
     }

With corresponding output:

vyatta@vyatta# run show wan-load-balance
Interface:  eth0
  Status:  active
  Last Status Change:  Wed Mar 30 19:03:59 2011
  +Test:  user  Script: /tmp/http_test.pl
    Last Interface Success:  0s
    Last Interface Failure:  n/a
    # Interface Failure(s):  0

Interface:  eth1
  Status:  failed
  Last Status Change:  Wed Mar 30 19:03:59 2011
  -Test:  user  Script: /tmp/http_test.pl
    Last Interface Success:  n/a
    Last Interface Failure:  0s
    # Interface Failure(s):  52

Scripts returns 0 for success, non-zero for failure.
