Add direct pernosco upload

[Keno]

I think there'd be two useful pieces of functionality here:

1. Basically implement what https://github.com/Pernosco/pernosco-submit/blob/master/pernosco-submit does here. pernosco-submit has a number of dependencies and is a bit of pain to set up - we should be able to just upload directly. The submission process is very similar to our own submission process (in that it's also an S3 upload), but there's some encryption going on.

2. Add the ability to copy a previously uploaded trace to pernosco, ideally by just doing an S3-side copy, but there may need to be a lambda involved for handling the encryption.

It would be nice to streamline pernosco authentication also. I always have trouble finding my credentials and I think from our experience here, the one click authentication is about what users are willing to tolerate.
