Django caches some information on HttpRequest objects, including the
headers dict, under the assumption that requests won’t be reused.

To provide a smoother experience of accessing a web public stream,
we don't ask user to login unless user directly requests a
`/login` URL.
Fixes#21690.
`cachify` is essentially caching the return value of a function using only
the non-keyword-only arguments as the key.
The use case of the function in the backend can be sufficiently covered by
`functools.lru_cache` as an unbound cache. There is no signficant difference
apart from `cachify` overlooking keyword-only arguments, and
`functools.lru_cache` being conveniently typed.

If an API request specified a `client` parameter, we were
already prioritizing that value over parsing the UserAgent.
In order to have these parameters logged in the `RequestNotes`
as processed parameters instead of ignored parameters, we add
the `has_request_variables` decorator to `parse_client` and
then process the potential `client` parameter through the REQ
framework.

Removes `client` parameter from backend tests using the
`POST /messages` endpoint when the test can use the default
`User-Agent` as the client, which is set to `ZulipMobile` for API
requests and a browser user agent string for web app requests.
Adds request as a parameter to json_success as a refactor towards
making `ignored_parameters_unsupported` functionality available
for all API endpoints.
Also, removes any data parameters that are an empty dict or
a dict with the generic success response values.
Given that these values are uuids, it's better to use UUIDField which is
meant for exactly that, rather than an arbitrary CharField.
This requires modifying some tests to use valid uuids.
Requests to the root subdomain weren't getting request_notes.realm set
even if a realm exists on the root subdomain - which is actually a
common scenario, because simply having one organization, on the root
subdomain, is the simplest and common way for self-hosted deployments.
This reverts commit cd93d0967f.
This check_or is redundant with check_union; it gives a misleading
error message for the non-matching case; and it has no type safety.

This utilizes the generic `BaseNotes` we added for multipurpose
patching. With this migration as an example, we can further support
more types of notes to replace the monkey-patching approach we have used
throughout the codebase for type safety.
Tuples cannot be deserialized from JSON.
While we do use these validators for other things, like event
dictionaries, we have migrated the API away from using those. The
last use was removed in 4f3d5f2d87

Instead of directly changing the `POST` attribute of a request, we
utilize the `HostRequestMock` initializer to produce requests with
different post data.
The decorators require the decorated function to be a valid view
function. This changes the way the mocked view functions and requests
are implemented such that we can invoke view functions without future
type errors.
Of the two other logging mocks left in this file, one checks
a logging call isn't made and another makes sure errors
aren't allowed by raising an exception as a side_effect
to the logger.
This migrates some mocked Request class and mocked request achieved
with namedtuple in test_decorators and test_mirror_users to use the
refactored HostMockRequest.
Since weakref cannot be used with namedtuple, this old way of mocking a
request object should be migrated to using HostRequestMock. Only after
this change we can extract client from the request object and store it
via ZulipRequestNotes.
If the user is logged in, we'll stick to rate limiting by the
UserProfile. In case of requests without authentication, we'll apply the
same limits but to the IP address.
