Print vitastor-cli help for ls-osds and user-modify aliases

vitastor-cli accepts ls-osds and user-modify, but --help does not list
them, so "vitastor-cli --help ls-osds" printed "Unknown command". Add
them to the help and to the docs, which also lacked the pgs alias in the
Russian version. Test that --help knows every name the CLI accepts.
