Download and parse bwauth files

Recently tor added its bandwidth authority files to the DirPort...

https://gitweb.torproject.org/torspec.git/commit/?id=365d371

We should add a parser and support in stem.descriptor.remote. This feature was added in tor 0.3.5 which the dirauths aren't yet running #26694 (moved) will update dir-spec.txt with the Tor version that add this feature once it's merged (#21377 (moved)). Gonna wait to see this working in practice before we add stem support.

This wasn't actually added in 0.3.5. It was meant to be but missed the release.

It should include a test that do something similar to:

>>> 
... import stem.descriptor
... import stem.descriptor.remote
... import stem.directory
>>> downloader = stem.descriptor.remote.DescriptorDownloader(
...   document_handler = stem.descriptor.DocumentHandler.DOCUMENT,
... )
>>> resource = '/tor/status-vote/next/bandwidth'
>>> query_args = {'endpoints': [('127.10.0.1', 2003)]}
>>> bw = downloader.query(resource, **query_args)
>>> bw.content
b'1544811454\nversion=1.2.0\nearliest_bandwidth=2018-12-12T15:02:35\nfile_created=2018-12-15T08:09:48\ngenerator_started=2018-12-15T08:06:50\nlatest_bandwidth=2018-12-14T18:17:34\nminimum_number_eligible_relays=3820\nminimum_percent_eligible_relays=60\nnumber_consensus_relays=6366\nnumber_eligible_relays=0\npercent_eligible_relays=0\nsoftware=sbws\nsoftware_version=1.0.3-dev0\n====='

As commented in comment:48:ticket:21377

Hi juga. Stem support and test coverage for bandwidth file DirPort downloads will need to await its implementation within tor (ticket #21377 (moved)). Is there anything in my court here at present?

Nope, you're right, we need to wait for #21377 (moved).

Hi juga, sorry for the loooong delay! Finally got around to adding this. Feel free to reopen if you'd like to have anything tweaked.
