This prevents `get_user_profile_by_api_key` from doing a sequential
scan.
Doing this requires moving the generation of initial api_key values
into the column definition, so that even bare calls to
`UserProfile.objects.create` (e.g. from tests) call appropriately
generate a random initial value.
This removes the validator argument for 0423_realmfilter_url_template,
which do not really alter the database schema. It otherwise fails
the migration because the filter_format_validator function is removed.
Migration 0094_realm_filter_url_validator is modified because we can no
longer refer to filter_format_validator.

This will later be used to expand matching linkifier patterns.
Making it nullable for now, but we will make it required in
the APIs.
As a part of this transition, we temporarily make url_format_string
nullable as well, which will be later removed. This allows us to
switch to populating url_template without caring about passing
url_format_string.
Note that the validators are imported in the migration because Django
otherwise diffs it and considers the schema to be different, generating
a migration, failing the "tools/test-migrations" test.

Use the built-in HTML escaping of Markup("…{var}…").format(), in order
to allow Semgrep to detect mistakes like Markup("…{var}…".format())
and Markup(f"…{var}…").

do_delete_users had two bugs:
1. Creating the replacement dummy users
with active=True
2. Creating the replacement dummy users with email domain set to
realm.uri, which may not be a valid email domain.
Prior commits fixed the bugs, and this migration fixes the pre-existing
objects.
get_object_from_key should be used when trying to fetch a Confirmation
object. There are some places that need to make
Confirmation.objects.filter(...) queries, so we can't completely ban the
pattern, but we can ban .get(...) and
.filter(..., confirmation_key=..., ...).
django.utils.translation.ugettext is a deprecated alias of
django.utils.translation.gettext as of Django 3.0, and will be removed
in Django 4.0.

This adds the is_user_active with the appropriate code for setting the
value correctly in the future. In the following commit a migration to
backfill the value for existing Subscriptions will be added.
To ensure correct user_profile.is_active handling also in tests, we
replace all direct .is_active mutation with calls to appropriate
functions.
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.)

The psycopg2.SQL API unfortunately doesn’t work with
django.db.migrations.RunSQL, so we need to take a detour into
PL/pgSQL for EXECUTE and format.
