Enable IPv6 support

To enable IPv6 support, perform the following steps:

1. Specify your internal registry's Portworx operator image path in your Portworx operator spec. Replace the line image: portworx/px-operator:<version_number> in the generated Portworx operator spec with the path to your internal registry operator image. For example:

   image: <image_registry_hostname>/<repo_name>/<image_name>:<tag>

2. If your internal registry is password protected, create a secret to store the credentials, then specify the internal registry access info in the Portworx Storage Cluster spec. For example:

   imagePullSecret: <secret_name>
   customImageRegistry: <image_registry_hostname>/<repo_name>

3. Specify the oci-monitor path in the internal registry. For example:

   spec:
     image: <image_registry_hostname>/<repo_name>/<image_name>:<tag>

4. For dual network deployments, specify network configuration. For example:

     network:
       dataInterface: <interface_name_for_data_traffic>
       mgmtInterface: <interface_name_for_mgmt_traffic>
