DVC should check credentials for AWS sooner

[greaber]

When pushing or pulling to/from S3, I often forget to set my AWS credentials. It takes a pretty long time before dvc realizes this, I guess because it does a lot of other work first. For instance, I just tested a dvc pull, and it takes about three and a half minutes before telling me it is unable to locate credentials.

On a side note, maybe there is some way to speed up the work that dvc pull and push need to do before they can start transferring files in general?

Hi @greaber ! Could you please upgrade to 0.94.0 (released yesterday) and see if that helps? @pmrowla has introduced some amazing optimizations since the last release, so they should significantly improve the experience. 🙂

Oh wow, this issue seems fixed in 0.94!
