[Security] Bump django from 1.10.4 to 2.2

[dependabot-preview]

Bumps django from 1.10.4 to 2.2. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects django
In Django 1.10.x before 1.10.8 and 1.11.x before 1.11.5, HTML autoescaping was disabled in a portion of the template for the technical 500 debug page. Given the right circumstances, this allowed a cross-site scripting attack. This vulnerability shouldn't affect most production sites since you shouldn't run with "DEBUG = True" (which makes this page accessible) in your production settings.

Affected versions: >= 1.10.0, < 1.10.8

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects django
Django 1.10 before 1.10.7, 1.9 before 1.9.13, and 1.8 before 1.8.18 relies on user input in some cases to redirect the user to an "on success" URL. The security check for these redirects (namely django.utils.http.is_safe_url()) considered some numeric URLs "safe" when they shouldn't be, aka an open redirect vulnerability. Also, if a developer relies on is_safe_url() to provide safe redirect targets and puts such a URL into a link, they could suffer from an XSS attack.

Affected versions: >= 1.10, < 1.10.7

Moderate severity vulnerability that affects django
A maliciously crafted URL to a Django (1.10 before 1.10.7, 1.9 before 1.9.13, and 1.8 before 1.8.18) site using the django.views.static.serve() view could redirect to any other domain, aka an open redirect vulnerability.

Affected versions: >= 1.10, < 1.10.7

Sourced from The GitHub Security Advisory Database.

Low severity vulnerability that affects django
In Django 1.11.x before 1.11.18, 2.0.x before 2.0.10, and 2.1.x before 2.1.5, an Improper Neutralization of Special Elements in Output Used by a Downstream Component issue exists in django.views.defaults.page_not_found(), leading to content spoofing (in a 404 error page) if a user fails to recognize that a crafted URL has malicious content.

Affected versions: < 1.11.18

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects django
Django 1.11.x before 1.11.19, 2.0.x before 2.0.11, and 2.1.x before 2.1.6 allows Uncontrolled Memory Consumption via a malicious attacker-supplied value to the django.utils.numberformat.format() function.

Affected versions: < 1.11.19
