`no_update` is not transmitted to the perceval backend.

From https://github.com/chaoss/grimoirelab-perceval/blob/8ed4fb18055b5cb0fe6fc67c80ab50b285e306df/perceval/backends/core/git.py#L375

        exgroup_fetch.add_argument('--no-update', dest='no_update',

we can set no-update to fetch all commits without updating the repository.

However, even if I set no-update = true in setup.cfg when I used sirmordred module, the parameter wasn't transmitted to the perceval backend.

I think the reason is that the no-update is hidden in grimoire_elk.elk.feed_backend. https://github.com/chaoss/grimoirelab-elk/blob/00b346623d8f3f0b4de901d25a0ef28e79a02545/grimoire_elk/elk.py#L81

Here, no-update is true which we set in parsed_args.

https://github.com/chaoss/grimoirelab-elk/blob/00b346623d8f3f0b4de901d25a0ef28e79a02545/grimoire_elk/elk.py#L148-L160

Here, no-update is not transmitted when we call ocean_backend.feed(**params).

And then, in the method ocean_backend.feed, we lost the no-update so that we would use the default value false for no-update in Git.fetch forever.

@xiao623 - Thank you for reporting this issue. You are right, the field no_update is not transmitted to perceval.
