Alex Vandiver d04db7c5fe webhooks: Remove repetitive argument to UnsupportedWebhookEventType.
The name of the webhook can be added by the webhook decorator.

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 Agrawal d9431a5e66 exceptions: Raise InvalidSubdomainError when realm is invalid.
When user requests for a realm that doesn't exists, we raise
a InvalidSubdomainError.

This reduces our effort at repeatedly ensuring realm is valid
in request in web-public queries.

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 81c28c1d3e realm: Allow only organization owners to deactivate a realm.
We now allow only organization owners to deactivate a realm.

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.

Anders Kaseorg fead14951c python: Convert assignment type annotations to Python 3.6 style.
This commit was split by tabbott; this piece covers the vast majority
of files in Zulip, but excludes scripts/, tools/, and puppet/ to help
ensure we at least show the right error messages for Xenial systems.

We can likely further refine the remaining pieces with some testing.

Mateusz Mandera 335b804510 exceptions: RateLimited shouldn't inherit from PermissionDenied.
We will want to raise RateLimited in authenticate() in rate limiting
code - Django's authenticate() mechanism catches PermissionDenied, which
we don't want for RateLimited. We want RateLimited to propagate to our
code that called the authenticate() function.

Eeshan Garg 8e10ab282a webhooks: Log unexpected webhook events separately.
This change serves to declutter webhook-errors.log, which is
filled with too many UnexpectedWebhookEventType exceptions.

Keeping UnexpectedWebhookEventType in zerver/lib/webhooks/common.py
led to a cyclic import when we tried to import the exception in
zerver/decorators.py, so this commit also moves this exception to
another appropriate module. Note that our webhooks still import
this exception via zerver/lib/webhooks/common.py.

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.

Eeshan Garg d9958610a4 webhook_decorator: Support notifying bot owner on invalid JSON.
Our webhook-errors.log file is riddled with exceptions that are
logged when a webhook is incorrectly configured to send data in
a non-JSON format. To avoid this, api_key_only_webhook_view
now supports an additional argument, notify_bot_owner_on_invalid_json.
This argument, when True, will send a PM notification to the bot's
owner notifying them of the configuration issue.

Eeshan Garg 538746fc65 webhooks: Stop raising an exception if stream does not exist.
webhook-errors.log file is cluttered with Stream.DoesNotExist

since check_message already sends the bot_owner a PM if the webhook
bot tries to send a message to a non-existent stream, we can ignore
such exceptions.

Greg Price 192ec7c0f6 middleware: Use a proper error code on CSRF failure.
This allows us to reliably parse the error in code, rather than
attempt to parse the error text.  Because the error text gets
translated into the user's language, this error-handling path
wasn't functioning at all for users using Zulip in any of the
seven non-English languages for which we had a translation for
this string.

Together with 709c3b50f which fixed a similar issue in a
different error-handling path, this fixes #5598.
