We can delete qos by specify ls and more parameters.
If CMS want to delete it exactly, it must specify detailed "match" field.
It's not an easy way, also maybe deleted by mistake.
This change adds a way to specify ls and uuid, which is optional.
You can still use the previous method to delete.

usage:
ovn-nbctl qos-del ls0 [UUID0]

Can you please add a few tests in the tests/ovn-nbctl.at which would help
in regressions ?

Thanks
