Session Rework

[james-d-elliott]

Description

Currently how sessions are managed is very limiting. There are several desirable elements that would be improved by developing the session implementation ourselves. This FR is intended on encompassing all of these elements into a single clear picture so we can adequately design our eventual implementation.

Use Case

Make the session implementation significantly more useful and easy to work with in development.

Details

Listed issues likely require internal development of a session implementation:

• Unlimited session time for specific users / domains / resources? #6119
• Use existing database as session storage #3821
• Listing and removing sessions user interface #1388

Is there an easy fix to avoid AAAA queries for now? My DNS server's logs are spammed via `AAAA´ queries to Redis; I'd say it's about 1 query per second, which may not be much processing-wise, but it clutters the DNS server logs, which is rather undesirable.
