Inconsistent unit of measure for journal size in system host-stor-update command

[Wendy Mitchell]

Brief Description
-----------------
Inconsistent cli journal size unit of measure in the system host-stor command (GiB used in most places but system host-stor-update using MiB)

Severity
--------
standard

Steps to Reproduce
------------------
Confirm consistent output in GiB for the journal size in the system host-stor commands

1. The size is in GiB in host-stor-list

$ system host-stor-list controller-0
+--------------------------------------+----------+-------+------------+--------------------------------------+-----------------------------+------------+----------+-----------+
| uuid | function | osdid | state | idisk_uuid | journal_path | journal_no | journal_ | tier_name |
| | | | | | | de | size_gib | |
+--------------------------------------+----------+-------+------------+--------------------------------------+-----------------------------+------------+----------+-----------+
| 4f2a6d16-2f25-4445-be16-596d612c0222 | osd | 1 | configured | 8571c401-d275-4e56-839b-45561ab83a14 | /dev/disk/by-path/pci-0000: | /dev/sdb2 | 1 | storage |
| | | | | | 00:1f.2-ata-2.0-part2 | | | |
| | | | | | | | | |
+--------------------------------------+----------+-------+------------+--------------------------------------+-----------------------------+------------+----------+-----------+

2. The size is in GiB in host-stor-add

$ system host-stor-add
usage: system host-stor-add [--journal-location [<journal_location>]]
                            [--journal-size [<size of the journal GiB>]]
                            [--tier-uuid [<storage tier uuid>]]
                            <hostname or id> [<function>] <idisk_uuid>
system host-stor-add: error: too few arguments

$ system help host-stor-add
usage: system host-stor-add [--journal-location [<journal_location>]]
                            [--journal-size [<size of the journal GiB>]]
                            [--tier-uuid [<storage tier uuid>]]
                            <hostname or id> [<function>] <idisk_uuid>

Add a storage to a host.

Positional arguments:
  <hostname or id> Name or ID of host [REQUIRED]
  <function> Type of the stor (default: osd)
  <idisk_uuid> uuid of disk [REQUIRED]

Optional arguments:
  --journal-location [<journal_location>]
                        Location of stor's journal
  --journal-size [<size of the journal (GiB)>]
                        Size of stor's journal, in GiB
  --tier-uuid [<storage tier uuid>]
                        storage tier to assign this OSD

3.
$ system host-stor-update --journal-location 4f2a6d16-2f25-4445-be16-596d612c0222 --journal-size
usage: system host-stor-update [--journal-location [<journal_location>]]
                               [--journal-size [<size of the journal MiB>]]
                               <osd stor uuid>
system host-stor-update: error: too few arguments

$ system help host-stor-update
usage: system host-stor-update [--journal-location [<journal_location>]]
                               [--journal-size [<size of the journal MiB>]]
                               <osd stor uuid>

Modify journal attributes for OSD.

Positional arguments:
  <osd stor uuid> UUID of osd[REQUIRED]

Optional arguments:
  --journal-location [<journal_location>]
                        Location of stor's journal
  --journal-size [<size of the journal (MiB)>]
                        Size of stor's journal, in MiB

4. $ system host-stor-update --journal-location cbfbf28f-d7b8-4437-9402-611787b1b6f7 --journal-size 10 3f9a6686-2b76-4278-b997-b029211d7632

Expected Behavior
------------------
Expect the journal size to consistently use the same units of measure (ie. GiB) thoughout for system host-stor commands

Actual Behavior
----------------
In step 3 and 4, there are inconsistencies in the unit representation for the journal size on $system host-stor-update operations.
eg.
system host-stor-update command in still using the units MiB
update command specifies 10 but it is converted to 10240

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

System Configuration

stx.4.0 / medium priority - inconsistency with storage system cli cmds

[Ghada Khalil (gkhalil)]

Lowering the priority - this is still a would-be-nice to fix, but should not gate stx.4.0 given it's a minor inconsistency with some cli cmds
