Add support for spec overrides when restoring AWX

[rooftopcellist]

SUMMARY

There are often times where you might want to override specific parameters on the AWX spec when restoring from a backup. One such case is when you want to extend the database PVC size.

To extend the storage size of your postgres PVC, with this change, you can now:

1. Create an AWXBackup
2. Create an AWXRestore with a spec_overrides entry for spec_overrides.postgres_storage_requirements.requests: 110Gi on your AWXRestore object
3. The new deployment will have any spec_overrides preferentially included on the new AWX CR spec.

Testing

First, I applied the following AWX CR

---
apiVersion: awx.ansible.com/v1beta1
kind: AWX
metadata:
  name: awx
  namespace: awx
spec:
  service_type: clusterip
  ingress_type: route
  no_log: false
  admin_password_secret: custom-admin-password
  postgres_storage_requirements:
    requests:
      storage: 10Gi
  extra_settings:
    - setting: MAX_PAGE_SIZE
      value: "500"

Then I created an AWXBackup:

---
apiVersion: awx.ansible.com/v1beta1
kind: AWXBackup
metadata:
  name: awxbackup-2022-11-3
  # namespace: awx
spec:
  deployment_name: awx
  no_log: false

Then I created an AWXRestore with a variety of spec_overrides:

---
apiVersion: awx.ansible.com/v1beta1
kind: AWXRestore
metadata:
  name: restore1
  namespace: awx
spec:
  backup_name: backup1
  backup_source: "Backup CR"
  deployment_name: new-awx
  no_log: false

  # New Overrides parameter in action
  spec_overrides:
    service_type: clusterip
    ingress_type: route
    no_log: false
    postgres_storage_requirements:
      requests:
        storage: 11Gi
    extra_settings:
      - setting: MAX_PAGE_SIZE
        value: "511"
      - setting: LOG_AGGREGATOR_LEVEL
        value: "'DEBUG'"
    node_selector: |
      kubernetes.io/os: linux

The resulting new-awx CR had everything present on it's spec and deployed successfully!
