Description of problem:
Since configmaps in 3.7 don't support the binaryData field so hooks don't currently work on 3.7. That will cause migmigration with hooks is stuck in running status.

Version-Release number of selected component (if applicable):
CAM 1.2

How reproducible:
Always

Steps to Reproduce:
1. Create service account in target cluster

$ oc new-project robot-target
$ oc create sa robot-target -n robot-target
$ oc adm policy add-cluster-role-to-user cluster-admin system:serviceaccount:robot-target:robot-target

2 Create a service account in source cluster

$ oc new-project robot-source
$ oc create sa robot-source -n robot-source
$ oc adm policy add-cluster-role-to-user cluster-admin system:serviceaccount:robot-source:robot-source

3. In source cluster deploy an application
$ oc new-project ocp-29918-hooks
$ oc new-app cakephp-mysql-persistent

4. Create a migration plan to migrate ocp-29918-hooks namespace with default values.

Continue to step 5 when you reach the "Hooks" screen to add the hooks.

5. Add PreBackup Hook for source cluster
Add this playbook in the playbook screen when creating the migration plan

Name: sourceprebackuphook
Ansible Playbook:
- hosts: localhost
  tasks:
  - name: Get Pods
    k8s_facts:
      kind: Pod
      namespace: "ocp-29918-hooks"
      label_selectors: "name=mysql"
    register: pod
    retries: 20
    until: pod.resources | length > 0

  - debug: msg={{ item.metadata.name }}
    loop: "{{ pod.resources }}"
    loop_control:
      label: "{{ item.metadata.name }}"

  - name: Get all namespaces using oc binary
    shell: "oc get namespaces"
    register: ns
    until: ns.rc == 0

  - debug: msg={{ item }}
    loop: "{{ ns.stdout_lines }}"
    loop_control:
      label: "{{ item }}"



Ansible Runtime Image: Leave the default value
Source Cluster:
    Servcie Account Name: robot-source
    Service Account Namespace: robot-source
Phase: PreBackup

6. Add PostBackup Hook for source cluster

Add this playbook in the playbook screen when creating the migration plan

Name: sourcepostbackuphook
Ansible Playbook:
- hosts: localhost
  tasks:
  - name: Get Pods
    k8s_facts:
      kind: Pod
      namespace: "openshift-migration"
      label_selectors: "app=migration"
    register: pod
    retries: 20
    until: pod.resources | length > 0

  - debug: msg={{ item.metadata.name }}
    loop: "{{ pod.resources }}"
    loop_control:
      label: "{{ item.metadata.name }}"

  - name: Get all namespaces using oc binary
    shell: "oc get namespaces"
    register: ns
    until: ns.rc == 0

  - debug: msg={{ item }}
    loop: "{{ ns.stdout_lines }}"
    loop_control:
      label: "{{ item }}"



Ansible Runtime Image: Leave the default value
Source Cluster:
    Servcie Account Name: robot-source
    Service Account Namespace: robot-source
Phase: PostBackup   6. The hook should be added without errors.

6. Add PreRestore Hook for target cluster

Add this playbook in the playbook screen when creating the migration plan

Name: tagetprerestorehook
Ansible Playbook:
- hosts: localhost
  tasks:
  - name: Get Pods
    k8s_facts:
      kind: Pod
      namespace: "openshift-migration"
      label_selectors: "app=migration"
    register: pod
    retries: 20
    until: pod.resources | length > 0

  - debug: msg={{ item.metadata.name }}
    loop: "{{ pod.resources }}"
    loop_control:
      label: "{{ item.metadata.name }}"

  - name: Get all namespaces using oc binary
    shell: "oc get namespaces"
    register: ns
    until: ns.rc == 0

  - debug: msg={{ item }}
    loop: "{{ ns.stdout_lines }}"
    loop_control:
      label: "{{ item }}"



Ansible Runtime Image: Leave the default value
Target Cluster:
    Servcie Account Name: robot-target
    Service Account Namespace: robot-target
Phase: PreRestore   

7. Add PostRestore Hook for target cluster

Add this playbook in the playbook screen when creating the migration plan

Name: tagetpostrestorehook
Ansible Playbook:
- hosts: localhost
  tasks:
  - name: Get Pods
    k8s_facts:
      kind: Pod
      namespace: "ocp-29918-hooks"
      label_selectors: "name=mysql"
    register: pod
    retries: 20
    until: pod.resources | length > 0

  - debug: msg={{ item.metadata.name }}
    loop: "{{ pod.resources }}"
    loop_control:
      label: "{{ item.metadata.name }}"

  - name: Get all namespaces using oc binary
    shell: "oc get namespaces"
    register: ns
    until: ns.rc == 0

  - debug: msg={{ item }}
    loop: "{{ ns.stdout_lines }}"
    loop_control:
      label: "{{ item }}"



Ansible Runtime Image: Leave the default value
Target Cluster:
    Servcie Account Name: robot-target
    Service Account Namespace: robot-target
Phase: PostRestore

8. Execute the migration of the migration plan


Actual results:
On CAM console, the migration is stuck in running status. 

Expected results:
the migration should be executed successfully.
