This should fix a class of bug where we forget to check if e.g. the appservice shouldn't be ratelimited.
We also check the `ratelimit_override` table to check if the user has ratelimiting disabled. That table is really only meant to override the event sender ratelimiting, so we don't use any values from it (as they might not make sense for different rate limits), but we do infer that if ratelimiting is disabled for the user we should disabled all ratelimits.
Fixes#9663
* SsoHandler: remove inheritance from BaseHandler
* Simplify the flow for SSO UIA
We don't need to do all the magic for mapping users when we are doing UIA, so
let's factor that out.
While working on https://github.com/matrix-org/synapse/issues/5665 I found myself digging into the `Ratelimiter` class and seeing that it was both:
* Rather undocumented, and
* causing a *lot* of config checks
This PR attempts to refactor and comment the `Ratelimiter` class, as well as encourage config file accesses to only be done at instantiation.
Best to be reviewed commit-by-commit.
* Rate-limiting for registration
* Add unit test for registration rate limiting
* Add config parameters for rate limiting on auth endpoints
* Doc
* Fix doc of rate limiting function

When guest_access changes from allowed to forbidden all local guest
users should be kicked from the room. This did not happen when
revocation was received from federation on a worker.
Presumably broken in #4141
This adds a flag loaded from the registration file of an AS that will determine whether or not its users are rate limited (by ratelimit in _base.py). Needed for IRC bridge reasons - see https://github.com/matrix-org/matrix-appservice-irc/issues/240.
pycharm supports them so there is no need to use the other format.
Might as well convert the existing strings to reduce the risk of
people accidentally cargo culting the wrong doc string format.
