These files should be applied on top of incoming OpenAPI in order
to add some extra keys such as x-mgc-name
to change the
command line interface name to use for a command or flag.
Apply using yaml_merge.py, example:
cd ..
python3 scripts/yaml_merge.py \
mgc/cli/openapis/vpc.openapi.yaml \
openapi-customizations/vpc.openapi.yaml
