Bug Description

Brief Description
-----------------
Currently, default platform memory reserve on AIO is calculated as 6000 MIB + 1000 MiB * # numa nodes. For a host with a single numa node, this means a reserve of 7000 MiB. It's been observed on AIO-SX hosts, deployed as subclouds with application pods running that the 80% alarm threshold can be hit.

Severity
--------
Minor

Steps to Reproduce
------------------
Deploy AIO-SX with single numa node as subcloud with application pods.

Expected Behavior
------------------
Platform memory usage should stay within alarm limits.

Actual Behavior
----------------
Platform memory usage exceeds major alarm threshold.

Reproducibility
---------------
Reproducible

System Configuration
--------------------
One node system

    Increase platform memory reserve on AIO hosts

    Increase memory reserve for AIO by 1000 MiB. Total memory reserve for
    AIO in MiB will be 5000 + 2000 + 1000 * number of numa nodes. This will
    give more headroom for AIO-SX subclouds with a single numa node.

screening: marking as low priority as there is a simple workaround to adjust the memory via CLI; therefore, this is not gating for stx.5.0

    Fix controller-0 downgrade failing to kill ceph

    kill_ceph_storage_monitor tried to manipulate a pmon
    file that does not exist in an AIO-DX environment.

    We no longer invoke kill_ceph_storage_monitor in an
    AIO SX or DX env.

    This allows: "system host-downgrade controller-0"
    to proceed in an AIO-DX environment where that second
    controller (controller-0) was upgraded.

    Fix file permissions failure during duplex upgrade abort

    When issuing a downgrade for controller-0 in a duplex upgrade
    abort and rollback scenario, the downgrade command was failing
    because the sysinv API does not have root permissions to set
    a file flag.
    The fix is to use RPC so the conductor can create the flag
    and allow the downgrade for controller-0 to get further.

    Fix bug rook-ceph provision with multi osd on one host

    Test case:
    1, deploy simplex system
    2, apply rook-ceph with below override value
    value.yaml
    cluster:
      storage:
        nodes:
        - name: controller-0
          devices:
          - name: sdb
          - name: sdc
    3, reboot

    Without this fix, only osd pod could launch successfully after boot
    as vg start with ceph could not correctly add in sysinv-database
