Description of the issue (please include outputs or screenshots if possible):
I am trying to patch a configmap that has two elements: roles and users.

roles: |
   - some values
users: |
   - some values

I want to remove the element users from the configmap when the value is null. The default patch strategy appears to be a strategic merge, but I want to do a regular merge patch. How do you specify the merge strategy when you call the patch_namespaced_config_map() API? Do you have to use patch_namespaced_config_map_with_http_info? And if so, how do you pass the merge strategy to it?
