Correct vitastor-cli help for rm, raw-ls, fix and rm-osd

- rm: the --exact and --matching descriptions were swapped. - raw-ls: show that --pool_id is required, and --pg_num unless --offset is given, and when the pool configuration fills in the rest. - fix: show --bad-osds as required. - rm-osd: describe -f, --allow-up and --allow-data-loss. Up OSDs are refused too, -f covers them and degraded/offline PGs, and --allow-data-loss covers incomplete ones and implies -f. Apply the same corrections to the CLI documentation.
