This patch deprecates the following args for `rally verify start` cmd:
Old New
tests-file -> load-list
xfails-file -> xfail-list
So now we have consistent args that allow us to manage the workflow for
a certain list of tests:
1. Arg 'load-list' - Run tests listed in the named file
2. Arg 'skip-list' - Skip run of tests listed in the named file
3. Arg 'xfail-list' - Consider tests listed in the named file as
expected failures
