* add docstring for `rally-manage db recreate`.
* updates `deprecated_args` to handle release and alternative arg.
* rename `--verification` and `task` to `--uuid` in `rally verify use` and
`rally task use`.(these arguments should have the same name across one
category). The old names are deprecated.
* rename destination of `--uuid`, `--uuid-1`, `uuid-2` arguments to
`verification`, `verification1`, `verification2` for consistent with other
destinations.
* remove `required=False` attribute setting for task_id in `rally task use`.
* fix attribute name in `default_from_global` for `report`
