Anders Kaseorg b7b7475672 python: Use standard secrets module to generate random tokens.
There are three functional side effects:

• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.

• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.

• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.

(The base32 alphabet is A-Z 2-7.  We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

Anders Kaseorg 3ffed617a2 mypy: Type simple generators as Iterator, not Iterable.
A generator that yields values without receiving or returning them is
an Iterator.  Although every Iterator happens to be iterable, Iterable
is a confusing annotation for generators because a generator is only
iterable once.

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.

Steve Howell 626ad0078d tests: Add uuid_get and uuid_post.
We want a clean codepath for the vast majority
of cases of using api_get/api_post, which now
uses email and which we'll soon convert to
accepting `user` as a parameter.

These apis that take two different types of
values for the same parameter make sweeps
like this kinda painful, and they're pretty
easy to avoid by extracting helpers to do
the actual common tasks.  So, for example,
here I still keep a common method to
actually encode the credentials (since
the whole encode/decode business is an
annoying detail that you don't want to fix
in two places):

    def encode_credentials(self, identifier: str, api_key: str) -> str:
        """
        identifier: Can be an email or a remote server uuid.
        """
        credentials = "%s:%s" % (identifier, api_key)
        return 'Basic ' + base64.b64encode(credentials.encode('utf-8')).decode('utf-8')

But then the rest of the code has two separate
codepaths.

And for the uuid functions, we no longer have
crufty references to realm.  (In fairness, realm
will also go away when we introduce users.)

For the `is_remote_server` helper, I just inlined
it, since it's now only needed in one place, and the
name didn't make total sense anyway, plus it wasn't
a super robust check.  In context, it's easier
just to use a comment now to say what we're doing:

    # If `role` doesn't look like an email, it might be a uuid.
    if settings.ZILENCER_ENABLED and role is not None and '@' not in role:
        # do stuff

Yago González 6a192ac84c utils: Move random API key generator as generate_api_key.
random_api_key, the function we use to generate random tokens for API
keys, has been moved to zerver/lib/utils.py because it's used in more
parts of the codebase (apart from user creation), and having it in
zerver/lib/create_user.py was prone to cyclic dependencies.

The function has also been renamed to generate_api_key to have an
imperative name, that makes clearer what it does.

hackerkid ea39fb2556 Add option for hosting each realm on its own subdomain.
This adds support for running a Zulip production server with each
realm on its own unique subdomain, e.g. https://realm_name.example.com.

This patch includes a ton of important features:
* Configuring the Zulip sesion middleware to issue cookier correctly
  for the subdomains case.
* Throwing an error if the user tries to visit an invalid subdomain.
* Runs a portion of the Casper tests with REALMS_HAVE_SUBDOMAINS
  enabled to test the subdomain signup process.
* Updating our integrations documentation to refer to the current subdomain.
* Enforces that users can only login to the subdomain of their realm
  (but does not restrict the API; that will be tightened in a future commit).

Note that toggling settings.REALMS_HAVE_SUBDOMAINS on a live server is
not supported without manual intervention (the main problem will be
adding "subdomain" values for all the existing realms).

Eklavya Sharma 10f2ec043d Fix zerver.lib.utils.generate_random_token.
generate_random_token used to return a value of type six.binary_type
and its return type was annotated as `str`.  This commit fixes that
by making it return a value of type `six.text_type` and updating
the annotation accordingly.
Also fix clashing annnotations.

config to configure it anyway:

STATSD_HOST = 'localhost'
STATSD_PREFIX = 'user'
