Kube Upgrade needs to raise/clear appropriate alarms based on its activity

[John Kung]

Brief Description
-----------------
There is an alarm defined for kube upgrade in progress
900.007 defined in fm-api ( FM_ALARM_ID_KUBE_UPGRADE_IN_PROGRESS)
however there is no code in sysinv to raise or clear that alarm.

Would be good to raise/clear the alarm so we are consistent between upgrades, patching, firmware
and k8s upgrade.

Note: When this is fixed, the VIM kube upgrade orchestration and DC kube upgrade orchestration should
also be re-tested to ensure the alarm does not block their execution.

Severity
--------

Minor: potential missing alarm; during orchestration there is a raised orchestration alarm
to indicate the state kube upgrade in progress; however, not if performed manually.

Steps to Reproduce
------------------

Start a kubernetes upgrade and check fm.
system kube-upgrade-start <some version>
fm alarm-list

Steps for setting up env to run a kubernetes upgrade are here:
https://docs.starlingx.io/configuration/k8s_upgrade.html

Expected Behavior
------------------
there should be an alarm (900.007)

Actual Behavior
----------------
no alarm for kube upgrade exists

Reproducibility
---------------
100% reproducible

System Configuration
--------------------
Can be done in any env that supports kube upgrade. (AIO-SX, AIO-DX or STD-DX)

Last Pass
---------
N/A

Timestamp/Logs
--------------
N/A

There are no logs, because this is an enhancement rather than an error or a failure.

Test Activity
-------------
Code Inspection

Workaround
----------
No need for a workaround, although the alarm could be manually raised.

    Kube Upgrade: Raise and clear kube upgrade in progress alarm

    The fm alarm 900.007 "Kubernetes upgrade in progress." is raised on start
    of kubernetes upgrade and cleared on completion of kubernetes upgrade.

    Prior to this commit, the 900.007 (FM_ALARM_ID_KUBE_UPGRADE_IN_PROGRESS)
    alarm was not being raised. It is already in the VIM ignore list, so
    it does not prevent the orchestrated kube upgrade operations.

    Verified on manual and VIM orchestrated kubernetes upgrade.
