[PATCH 1/9] xfstests: fsstress add command line style output for show_opts

[Dmitry Monakhov <dmonakhov@xxxxxxxxxx>]

Once some combination of seed+fs_ops result in regression it is
reasonable to document that combination. It is usefull to dump
that configuration in command line style. Later this line may be
simply hardcoded in to regression test.
