Fix tempest init logic

The tempest init was checking if the workspace/etc directory exists, and
were creating a new workspace without pass a name, the default is
workspace, but passing a --name ensure it won't break if tempest decides
to change it.
Also, the rename command only change the name in the
$HOME/.tempest/workspace.yml, it doesn't change the path for the
particular workspace. The same happens with the move command, it just
update the path on the workspace.yml file.
With this patch, the tempest workspace is being moved properly to a
workspace_$CURDATE, all the files are copied to the new workspace,
delete the old workspace directory, and call tempest init properly.

Also adding tripleo upgrade job as nv for now, since this issue only
happen in upgrade jobs.
