Providing sweep_id

[BjarnePfitzner]

First of all thanks for writing this hydra plugin, it was exactly what I was looking for.

Unfortunately providing a sweep_id does not work for me, I get the following traceback:

Traceback (most recent call last):

    raise ValueError(
ValueError: Input cfg is not an OmegaConf config object (str)

By simply changing line 455 to self.sweep_id, I could circumvent this error. Instead, I think the whole block from ll. 454 to 458 can be deleted.

Also, for a future documentation, please note that the sweep_id apparently has to follow the structure {entity}/{project}/{sweep_id}. This was not obvious to me, even though it may be to others.
