This line previously departed from the convention of coalescing down to
the original value specified in `lms/envs/common.py`.

Now, the setting can fall back to its default value from `common.py`,
instead of only respecting the value loaded from JSON (or `None` if not
defined).

General good-practice cleanup requested by @jibsheet. Also includes some
pylint fixes myh editor flagged during this cleanup.

aws.py redefines the default queues in order to expose cross-environment
work. The new recalculate grades routing key shgould use that value
rather than the default defined in common.py.

Adds a context-sensitive link to learner documentation from the LMS. The base URL defaults to Open edX learner doc and can be overridden with the base URL for edx.org learner doc.  Also relabels the tab for support from help to support.

This setting is necessary to avoid django-storages applying a security token to S3 URLs.

We use S3 for a number of uploads. Boto, by default, includes a auth querystring on the returned URLs. Since these uploads are public, there is no need for this querystring. Additionally, the long length URLs cause problems when API consumers need to store the URLs. This commit resolves this problem by removing the auth querystring.

- Updated to latest versions of boto and django-storages-redux packages
- Added AWS_QUERYSTRING_AUTH setting to remove the querystring values
