Eeshan Garg 2393342e03 webhooks/jira: Handle anomalous payloads properly.
We recently ran into a payload in production that didn't contain
an event type at all. A payload where we can't figure out the event
type is quite rare. Instead of letting these payloads run amok, we
should raise a more informative exception for such unusual payloads.
If we encounter too many of these, then we can choose to conduct a
deeper investigation on a case-by-case basis.

With some changes by Tim Abbott.

Sahil Batra e6106cb334 invites: Update error message when max limit for the day is reached.
This commit updates the error message returned when the maximum
invite limit for the day. We update the error returned by API to
only mention that the limit is reached and add the suggestion
to use multi-use link or contact support in the message shown
in webapp.

m-e-l-u-h-a-n aea31eb31f api: Add REALM_DEACTIVATED error code.
In `validate_account_and_subdomain` we check
if user's realm is not deactivated. In case
of failure of this check, we raise our standard
JsonableError. While this works well in most
cases but it creates difficulties in handling
of users with deactivated realms for non-browser
clients.

So we register a new REALM_DEACTIVATED error
code so that clients can distinguish if error
is because of deactivated account. Following
these changes `validate_account_and_subdomain`
raises RealmDeactivatedError if user's realm
is deactivated.

This error is also documented in
`/api/rest-error-handling`.

Testing: I have mostly relied on automated
backend tests to test this.

Fixes #17763.

sahil839 37c8505435 message: Raise exception when trying to mirror an already sent message.
Previously we were just returning a dict containing a message id when
trying to mirror a already sent message in 'zephyr_mirror' cases.

This commit changes this behaviour to raise an exception when trying
to mirror an already sent message by adding a new exception class
ZephyrMessageAlreadySentException and then the caller returns the
message_id directly, instead of calling do_send_messages which also
returns a list of size one containing the message_id only.

This is a prep commit for changing the return type of check_message to
be a dataclass instead of a Dict as now we have only single output for
check_message.

Mateusz Mandera 43a0c60e96 exceptions: Make RateLimited into a subclass of JsonableError.
This simplifies the code, as it allows using the mechanism of converting
JsonableErrors into a response instead of having separate, but
ultimately similar, logic in RateLimitMiddleware.
We don't touch tests here because "rate limited" error responses are
already verified in test_external.py.

Alex Vandiver 9ea9752e0e webhooks: Rename UnexpectedWebhookEventType to UnsupportedWebhookEventType.
Any exception is an "unexpected event", which means talking about
having an "unexpected event logger" or "unexpected event exception" is
confusing.  As the error message in `exceptions.py` already explains,
this is about an _unsupported_ event type.

This also switches the path that these exceptions are written to,
accordingly.

Aman fd5423a8f9 exceptions: Extract json_unauths into MissingAuthenticationError.
We raise two types of json_unauthorized when
MissingAuthenticationError is raised. Raising the one
with www_authenticate let's the client know that user needs
to be logged in to access the requested content.

Sending `www_authenticate='session'` header with the response
also stops modern web-browsers from showing a login form to the
user and let's the client handle it completely.

Structurally, this moves the handling of common authentication errors
to a single shared middleware exception handler.

sahil839 ca1a8ac78f streams: Allow stream admin to update and deactivate streams.
The new Stream administrator role is allowed to manage a stream they
administer, including:
* Setting properties like name, description, privacy and post-policy.
* Removing subscribers
* Deactivating the stream

The access_stream_for_delete_or_update is modified and is used only
to get objects from database and further checks for administrative
rights is done by check_stream_access_for_delete_or_update.

We have also added a new exception class StreamAdministratorRequired.

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

sahil839 6d667dbe53 realm owner: Add ability to change realm owner status of user.
This commit adds some basic checks while adding or removing
realm owner status of a user and adds code to change owner
status of a user using update_user_backend.

This also adds restriction on removing owner status of the
last owner of realm. This restriction was previously on
revoking admin status, but as we have added a more privileged
role of realm owner, we now have this restriction on owner
instead of admin.

We need to apply that restriction both in the role change code path
and the deactivate code path.

Anders Kaseorg 4d04fa3118 compose: Rewrite Zoom video call integration to use OAuth.
This reimplements our Zoom video call integration to use an OAuth
application.  In addition to providing a cleaner setup experience,
especially on zulipchat.com where the server administrators can have
done the app registration already, it also fixes the limitation of the
previous integration that it could only have one call active at a time
when set up with typical Zoom API keys.

Fixes #11672.

This change serves to declutter webhook-errors.log, which is

Eeshan Garg 998437c123 check_message: Support sending stream messages by ID.
This commit also contains the following auxiliary changes:
* Adds a custom exception, StreamWithIDDoesNotExist for when
  a stream with a given ID does not exist because the error
  message returned by StreamDoesNotExist only makes with stream
  names, not IDs.
* Adds a new helper, get_stream_by_id_in_realm, which is similar
  to get_user_profile_by_id_in_realm (introduced in #10391).
* Adds a helper, validate_stream_id_with_pm_notification, which
  returns the Stream object associated with a given ID and also
  handles PM notifications to the bot owner if the message was
  sent by a bot and if the stream does not exist or has no
  subscribers.
* Modifies the message sent by send_pm_if_empty_stream to
  accommodate stream IDs.

Note that all of the above changes are required before check_message
can be modified to support stream IDs.
