Better dynamic append_name function.

[utf]

I would make a new update_name method that has more functionalities:

• Update the name without adding prefix/suffix (this is already available if you just do some_job.name = 'mynewname', but not in a dynamic way)
• Filters similar to update_metadata and others

API of this method could be:

def update_metadata(
        self,
        newname: str | None = None,
        prefix: str | None = None,
        suffix: str | None = None,
        name_filter: str = None,
        function_filter: Callable = None,
        dynamic: bool = True,
    ):

Then the append_name can just be used by this method if prefix and/or suffix is provided. (and the dynamic in append_name is not needed, I guess it would be better/less confusing if it is only in one place)

Not sure if it is absolutely essential, but it would make thing consistent with the rest of the update_* methods. (and I guess it would not be a huge work but again, it's all a matter of "is it needed and worth it if there is no use case right now ?")
