Add component tests for the scstadmin management interface, including
state preservation after rejected commands. Use scst_local and
vdisk_nullio to cover devices, targets, LUN mappings, initiator groups,
ALUA and configuration save/restore without physical storage.
Provide a shared runner with explicit configuration, host locking,
bounded command logs and JSON/JUnit reports. Select specs through labels
and focus before preparing the host, and reject empty selections. Parse
scstadmin output, including session attributes and LUN mappings, through
common helpers covered by framework tests.
Load checkout modules in suite setup, optionally build them first, and
unload them after successful cleanup. Add common Make targets for
framework checks, test selection and live runs, with setup documentation.
