Section Number and Name: 10.52.8. hammer repository update

Describe the issue: 
The following options are missed in the documentation but are available in the help section:
~~~
 --docker-digest DIGEST                                    Container Image manifest digest
 --docker-tag TAG                                          Container Image tag                                      
~~~

It would be great to have them described with their purpose because this makes it look like we can update the docker repo so we can specify a specific tag to be synced but it does not work.

Failed to upload tag 'latest' to repository.

Suggestions for improvement: 
Better description of both options
