Start by reading the existing AdminResources REST APIs and command-line implementation. Trace how SQL session metadata is currently handled before assessing the requested metadata storage, engine and session listing/deletion commands, and count limits. Done means the listed REST and command-line enhancements are implemented, with documentation handled in separate PRs.
