inconsistency in zfsnode's zpool stats representation

[abhilashshetty04]

What steps did you take and what happened:

zfsnode resource capacity fields are represented in bytes and human-readable. Its bound to change also with every update on CR.

For example:

Here are 2 pools with no zvols on different nodes. Both zpools were created on 30G disk.

apiVersion: zfs.openebs.io/v1
kind: ZFSNode
metadata:
  creationTimestamp: "2025-01-30T06:53:24Z"
  generation: 2
  name: node-0-309787
  namespace: puls8
  ownerReferences:
  - apiVersion: v1
    controller: true
    kind: Node
    name: node-0-309787
    uid: d4ae440a-2fcc-487e-a056-8b1af6de985a
  resourceVersion: "39456"
  uid: d58cd02d-66ed-4921-ad44-a2ae39bc7557
pools:
- free: 29966204Ki
  name: zfspv-pool
  used: 99Ki
  uuid: "965947675669908193"
 
[nix-shell:~/mayarepo/openebs]# kubectl get zfsnodes node-1-309787 -n puls8 
apiVersion: zfs.openebs.io/v1
kind: ZFSNode
metadata:
  creationTimestamp: "2025-01-30T06:53:31Z"
  generation: 2
  name: node-1-309787
  namespace: puls8
  ownerReferences:

    controller: true
    kind: Node

  name: zfspv-pool
  used: "99840"
  uuid: "10029612145612829144"

Here 1st pool is in human readable 2nd is in bytes. Now same 2 pools after getting 1 volumes each

 kubectl get zfsnode node-0-309787 node-1-309787 -oyaml
apiVersion: v1

  resourceVersion: ""

Here its mixed, each pool has 1 metric in human readable and other in bytes.

What did you expect to happen:
Everythin should be in bytes or human reable. should be consistent.
