Updater: Way to disable hash prefix for consistent_snapshot

See original GitHub issue

Currently if the repository is consistent_snapshot, Updater will prefix the target filename with the hash when constructing the download URL. In the Warehouse case this is not wanted (warehouse target file paths are “consistent”, even if the filenames are not).

This is an example of a working URL:

https://files.pythonhosted.org/packages/ca/ab/5e004afa025a6fb640c6e983d4983e6507421ff01be224da79ab7de7a21f/Django-3.0.8-py3-none-any.whl

But currently Updater will try to download

https://files.pythonhosted.org/packages/ca/ab/5e004afa025a6fb640c6e983d4983e6507421ff01be224da79ab7de7a21f/caab5e004afa025a6fb640c6e983d4983e6507421ff01be224da79ab7de7a21f.Django-3.0.8-py3-none-any.whl

If there is no way to figure this out automatically, then there should probably be a way to tell Updater that I Know What I’m Doing, don’t prefix filenames.

I guess modifying targetinfo between get_one_valid_targetinfo() and download_target() is not a great idea: the use of schemas for input data is actively trying to prevent this sort of thing.

That leaves us with the last option: Add a boolean argument to Updater API (either Updater __init__() or download_target()). It’s ugly but I don’t have better ideas ATM.
