Bug Description

Brief Description
-----------------
When controller-1 is removed from a healthy AIO-DX environment, its OSDs are not removed from ceph, causing difference in the amount of OSDs being shown by Ceph and StarlingX.

Severity
--------.
Standard.

Steps to Reproduce
------------------
1) Make sure to have a healthy AIO-DX installed. Make sure to have a single OSD from controller-0 and another one from controller-1.

2) Remove controller-1 by using command "system host-delete".

3) Verify that ceph displays 2 OSDs instead of 1.

Expected Behavior
------------------
After removing controller, ceph should remove the OSDs associated to the removed controller.

Actual Behavior
----------------
OSD is not removed from ceph after removing the controller.

Reproducibility
---------------
Reproducible.

System Configuration
--------------------
AIO-DX where controller-0 and controller-1 should have a single OSD for each one.

Branch/Pull Time/Commit
-----------------------
BUILD_ID="20210306T023358Z"

Last Pass
---------

Timestamp/Logs
--------------
No collected logs because this is easy to reproduce.

Test Activity
-------------
Evaluation.

Workaround
----------
Steps below should be made for each OSD associated to the removed controller:

ceph osd crush remove osd.<osd_num>
ceph auth del osd.<osd_num>
ceph osd rm <osd_num>

    Delete ceph stor when removing controller

    When removing controller from cluster, its OSD is not being removed
    from ceph. This happens when removal is made by issuing "host-delete"
    command.

    This commit adds a call to remove the OSD from Ceph when controller is
    removed.

    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
