fix(crd): remove omitempty tag from CSPI status fields

[mittachaitu]

This PR does the following changes:

• Removes the omitempty tag on CSPI status fields.
  If omitempty tag is provided then default values are
  not shown in the output of kubectl get cspi <cspi_name> -o yaml.
• Set the priority value as 1 for ALLOCATED and TYPE printer columns.

Without this PR output of cspi:

kubectl get cspi -n openebs
NAME                     HOSTNAME    ALLOCATED   FREE    CAPACITY     READONLY   PROVISIONEDREPLICAS   HEALTHYREPLICAS   TYPE     STATUS   AGE

With changes in this PR:

kubectl get cspi -n openebs

Note to reviewers:

• Deployed the cstor-operator of 1.12.0 version YAMLs and CRDs.
• Provisioned the CSPC based pool.
• Upgraded the control plane to use modified CRDs and images(images were built locally).
  Observation: No errors were shown on the logs and able to create CSPI without status.
• Upgraded the CSPC to the latest version. CSPC was upgraded and no errors were shown

Zero-values and nil pointers are considered empty. If we want to output a 0, we should have used pointer types something like *int32 , *bool.
