Retrieve secrets using Secret Management Service

Retrieve secrets using Secret Management Service

Integrate with OSDF by retrieving stored secrets using SMS
Application code remains in tact as the secrets are preloaded
and stored in config. The configs in clear text will be deprecated
eventually. OOM needs to load aaf-sms and preload secrets
before oof deployment.

Updated to use domain name instead of domain uuid.
