Bug 28272: Prevent api spec to accept extra parameters

Bug 28272: Prevent api spec to accept extra parameters

Some of our definition files are missing { additionalProperties: false }
We must have it to make sure all properties are defined and prevent the
spec to accept extra parameters (being more strict but also allowing to
catch errors more easily)

grep -rL additionalProperties api/v1/swagger/definitions/*.json
