Create Backup of all resources and then restore the backup of only pods and deployments (include multiple resources)

[jaais0n]

Issue/Feature Description:
Test Case Precondition:

1. Kahu project installed in given name-space (test-kahu)
2. All below pods should be up and running:
   a. backup service
   b. Meta service with nfs provider
   c. nfs-server
3. Metadata location is created already
4. Namespace test-ns is created and contains some of the kubernetes resources
   Test Case steps:
5. Create below backup CR using kubectl command
   (use kubectl create -f <backup.yaml>)
   apiVersion: kahu.io/v1
   kind: Backup
   metadata:
   name: backup-Kahu-0001
   spec:
   includeNamespaces: [test-ns]
   metadataLocation: nfs
6. Use kubectl describe backup -n test-kahu
7. Get inside nfs server pod and check for the content inside mount path given
   (use command kubectl exec -ti -n test-kahu /bin/sh)
8. Create a restore CR on new namespace (restore-ns)
   apiVersion: kahu.io/v1
   kind: Restore
   metadata:
   name: restore-Kahu-0001
   Spec:
   backupName: backup-Kahu-0001
   includeResources:

• name:
  kind: Pod
  isRegex: true
• name:
  kind: Deployment
  isRegex: true
  namespaceMapping:
  test-ns : restore-ns
  Expected Result:

1. In step 2,
   a) Verify that backup stage is Finished and State is Completed
   b) Verify the resource list in status shows all the required resources
2. In step 3, verify that
   a) tar file is created with name of backup
   b) After untar file, All resources in the namespace test-ns are backuped.
3. In step4, verify that
   a) Only pods and deployments from the Backed up resources are up in new namespace
   restore-ns
   Why this issue to fixed / feature is needed(give scenarios or use cases):
   This is a testcase which is to automated to make sure deployment is properly backed up and
   restored
   How to reproduce, in case of a bug:
   Other Notes / Environment Information: (Please give the env information, log link or any
