GONRG-4713: Upgrade bootstrapping of initial accounts (enable multi SA)
- Added JDBC-specific tenant init service
- Added possibility to bootstrap individual service principals via
InitApi POST body
and provisioning JSONs - Added possibility to pass empty JSON object and disable init with additional SA (to decrease impact on other providers)
- Added template JSONs for service accounts
