Bug Description

The hbsAgent is not clearing its alarms over process startup in AIO SX system like it does on all other system types.

Severity
--------
Minor: Double fault case ; pmond failure that recovers over a hbsAgent process failure.
       Stuck 'pmond' process Alarm. This is the only alarm that the hbsAgent could assert in AIO SX

Can lead to a stuck alarm if the alarm condition clears over the hbsAgent restart,
Alarm can remain stuck until the alarm condition re-occurs and clears again without hbsAgent restart.

Steps to Reproduce
------------------
Step 1. kill pmond until the alarm is raised
Step 2. then allow it to recover and restart hbsAgent at the same time.

Expected Behavior
------------------
pmond alarm gets cleared only to be re-raised if the pmond process continues to be failed.

Actual Behavior
----------------
No attempt is made to clear the pmond alarm.

Reproducibility
---------------
100% with the aforementioned steps

System Configuration
--------------------
AIO SX

Branch/Pull Time/Commit
-----------------------
Current starlingx/master

Last Pass
---------
Test escape.

Timestamp/Logs
--------------
Issue does not produce any error logs.
Issue is understood by maintenance core prime/developer.

Test Activity
-------------
Stress testing

Workaround
----------
Manually clear alarm using fm cli.

    Add /pxeboot/grubx64.efi symlink for UEFI pxeboot

    UEFI pxeboot with shim.efi looks for the grubx64.efi in the tftpboot
    root directory. This update creates a symlink to the
    /pxeboot/EFI/grubx64.efi file in /pxeboot.

    Fix enabling heartbeat of self from the peer controller

    This issue only occurs over an hbsAgent process restart
    where the ready event response does not include the
    heartbeat start of the peer controller.

    This update reverts a small code change that was
    introduced by the following update.

    https://review.opendev.org/c/starlingx/metal/+/788495

    Remove the my_hostname gate introduced at line 1267 of
    mtcCtrlMsg.cpp because it prevents enabling heartbeat
    of self by the peer controller.

    Improved maintenance handling of spontaneous active controller reboot

    Performing a forced reboot of the active controller sometimes
    results in a second reboot of that controller. The cause of the
    second reboot was due to its reported uptime in the first mtcAlive
    message, following the reboot, as greater than 10 minutes.

    Maintenance has a long standing graceful recovery threshold of
    10 minutes. Meaning that if a host looses heartbeat and enters
    Graceful Recovery, if the uptime value extracted from the first
    mtcAlive message following the recovery of that host exceeds 10
    minutes, then maintenance interprets that the host did not reboot.
    If a host goes absent for longer than this threshold then for
    reasons not limited to security, maintenance declares the host
    as 'failed' and force re-enables it through a reboot.

    With the introduction of containers and addition of new features
    over the last few releases, boot times on some servers are
    approaching the 10 minute threshold an...
