Alarm audit is happening too frequently during VIM orchestration

[Bart Wensley]

Brief Description
-----------------
When the VIM does runs orchestration, it periodically queries alarms to keep track of the health of the system. The intent was that this should be done every 30 seconds, but the code is currently doing this query approximately every 4 seconds for Firmware, Upgrade and Kubernetes Upgrade orchestration. The query is being done at the correct interval for Patch orchestration.

There is no real functional impact - just unnecessary messaging from the VIM to the Fault Management component and extra logs in nfv-vim.log.

Severity
--------
Minor

Steps to Reproduce
------------------
Run one of the above mentioned orchestrations with the VIM.

Expected Behavior
------------------
Alarms should be audited roughly every 30 seconds.

Actual Behavior
----------------
Alarms are audited every 4 seconds.

    Reset alarm timers back to 30 after orch sets them to 2

    The alarm audit is set to 2 seconds by an alarm callback.
    Once that callback has been processed, need to reset the
    timer back to its default of 30 seconds.

    Note: Patch orch did not encounter this issue, because its
    audit called other code after the alarm callback, which reset
    the timer.
