Get HA test case results on failure

Get HA test case results on failure

Now, yardstick HA test cases (which have 'sla action: monitor') do
not output results if the test case SLA validation fails.
This patch modifies the task runner and the serviceHA scenario so
that during an SLA validation failure the test result data is
captured correctly.

Do similar changes in the general scenario.
