Update git submodules

* Update docs/submodules/oom.git from branch 'master'
  to b6e666836146077d9062357399f9fb725e752ba1
  - Merge "[COMMON] Use "" instead of {} as a default value to avoid warning"
  - [COMMON] Use "" instead of {} as a default value to avoid warning
    
    After we upgraded our helm version we started getting below issues
    with emails:
    
    Warning: Merging destination map for chart 'curator'.
    Overwriting table item 'image', with non table value:
    onap/sdnc-image:1.8.2
    
    To fix this let's just use "" instead of () for our daily operations.
