{code}
The validation API should tolerate
# services with no recommendations
# services with no configurations input (config-type key not provided)
The second case happens when I am editing only YARN service configs, and I do
not have configs for all the other services. In such a case, the
configs-validation call is made with only YARN config-types (yarn-env,
yarn-site, etc.). All other config-types are not provided. So for such a call,
validation for other services (Oozie, HDFS, etc. should not be performed). So,
basically we validate a service configs, only if its config-types are present.
