[Feature] Data Admin service account whitelist
Data Admin is a role that has permission to all the data. Ideally, there is a data admin permission group and will be automatically granted data permission whenever this is new data group created. The logic will be moved to osdu together with osdu entitlements v2 service. The current implementation of the osdu entitlements service does not support group hierarchy yet, so as a stop-gap solution, we implement a static configuration file to whitelist all the data admin service accounts and implement the logic to return all data groups for the whitelisted service accounts.
